April 15, 2010 H24 - Module Hardware Description 1
Chapter 1: Introduction
The H24 is the newest member of Motorola's embedded cellular modules family.
Designed with Tri bands WCDMA & quad band GSM capabilities, which supports WCDMA
bands: B1-2100, B4-1700, B2-1900, B5 -850 & B8-900 with HSPA capability and four GSM
bands - 850/900/1800/1900 MHz, with GPRS/EGPRS multislot class 12. H24 can operate on any
GSM/GPRS/EGPRS/WCDMA/HSPA network to provide voice and data communications.
The H24 is similar to a condensed cellular phone core, which can be integrated into any system or
product that needs to transfer voice or data information over a cellular network. Thus, it
significantly enhances the system's capabilities, transforming it from a standalone, isolated
product to a powerful high-performance system with global communications capabilities.
The H24 is designed as a complete GSM/WCDMA communications solution with all the
controls, interfaces and features to support a broad range of applications:
•A powerful audio interface
•A large set of indicators and control signals
•Several advanced power-saving modes
•A variety of serial communications solutions.
All these features and interfaces are easily controlled and configured using a versatile AT
command interface that provides full control over the H24 operation.
The H24 control and indication interface extends its capabilities beyond GSM communications.
This includes an A/D and GPIO interface, and a regulated output voltage for supplying external
circuits. With these interfaces, the H24 can operate and control external applications and receive
feedback from external environment and circuits.
The H24 interface design, using a single 70 pin board-to-board connector, through which all
application interfaces are managed, facilitates fast and easy integration. It significantly shortens
the development process, and minimizes the product's time to market.
The H24 is extremely compact in size with a slim mechanical design, which makes it space
saving on the application board and easily fitted into any board design.
The advanced power supply management significantly reduces power consumption to a
necessary minimum and prolongs battery life.

Power Supply
14 H24 - Module Hardware Description April 15, 2010
Power Supply
The H24 power supply must be a single external DC voltage source of 3.3V to 4.2V. The power
supply must be able to sustain the voltage level during a GSM transmit burst current surge, which
may reach 2.0A.
The H24 interface connector has 8 contacts for the main power supply, as described in Table 2-2.
All these contacts must be used for proper operation.
Important: Do not operate the H24 out of its electrical or environmental limits. Refer to the
specifications chapter for details of these limits.
Important: The H24 does not incorporate a hard reset capability. The user should implement a
power removal mechanism for hard resetting the unit when needed. This action will
be performed with care as it could cause damage to the H24.
Power Supply Design
Special care must be taken when designing the power supply of the H24. The single external DC
power source indirectly supplies all the digital and analog interfaces, but also directly supplies the
RF power amplifier (PA). Therefore, any degradation in the power supply performance, due to
losses, noises or transients, will directly affect the H24 performance.
The burst-mode operation of the GSM transmission and reception, draws instantaneous current
surges from the power supply, which causes temporary voltage drops of the power supply level.
The transmission bursts consume the most instantaneous current, and therefore cause the largest
voltage drop. If the voltage drops are not minimized, the frequent voltage fluctuations may
degrade the H24 performance.

Figure 2-4 illustrates the power supply behavior during GSM transmission.
Figure 2-4: Transmission Power Drops
Note: 1 TX slot is shown.
It is recommended that the voltage drops during a transmit burst will not exceed 300mV,
measured on the H24 interface connector. In any case, the H24 supply input must not drop below
the minimum operating level during a transmit burst. Dropping below the minimum operating
level may result in a low voltage detection, which will initiate an automatic power-off.
To minimize the losses and transients on the power supply lines, it is recommended to follow
these guidelines:
•Use a 1000 uF, or greater, low ESR capacitor on the H24 supply inputs. The capacitor should
be located as near to the H24 interface connector as possible.
•Use low impedance power source, cabling and board routing.
•Use cabling and routing as short as possible.
•Filter the H24 supply lines using filtering capacitors, as described in Table 2-3.

Power On/Off Operation
The H24 power on and off process includes two primary phases, which are indicated at the
interface connector by the hardware output signals RESET_N and CTS_N.
The RESET_N signal indicates whether H24 is powered on or off.
When this signal is enabled (low), H24 is powered-off. When it is disabled (high), H24 is
powered-on.
The CTS_N signal complys with RS-232 standard. When this signal is high, the H24 serial
interface is disabled. When it is low, the serial interface is enabled, and H24 is ready to
communicate.
Important: The timing shown in the diagrams below depends on network response time.
Turning the H24 On
When the H24 power supply is stable above the minimum operating level and H24 is powered
off, only the internal RTC timer is active.
When H24 is turned on, by any of the methods described below, it will first perform an automatic
internal system-test, during which basic functions are verified. The system-test duration is
typically 3 seconds (Depends on network coverage). When the system-test has completed H24
resumes normal operation.
During the internal system-test process H24 may toggle several interface signals, which are
visible to the application. These signals do not represent any valid state or data, and should be
ignored by the customer application until the system-test has completed.
Power Supply Turn-on
When the H24 is powered for the first time, it will switch on only in case that a valid reason was
detected (IGN, ON_N activation), otherwise it will stay off.
Power On/Off Operation
20 H24 - Module Hardware Description April 15, 2010
The ON_N and IGN signals will be active and responding only after the power supply to the H24
is stable above the minimum operating level. Therefore, the ON_N and IGN signals must not be
used for at least 100 milliseconds after applying power to H24.
Figure 2-5: Power Supply Turn On
Turning the H24 On Using ON_N
The ON_N input signal is set high by an internal pull-up resistor whenever a power supply is
applied to H24. Therefore, it is recommended to operate this signal using an open collector/drain
circuit connection.
Asserting the ON_N signal low for a minimum of 500 milliseconds (0.5 seconds) and a maximum
of 1.5 seconds will cause the H24 to turn-on.
Asserting the ON_N signal low for more than 1.5 seconds may cause the H24 to interpret the
signal as a power-off command, and turn off immediately after turning on.
Figure 2-6: Turning the H24 On Using ON_N
Chapter 2: Hardware Interface Description
April 15, 2010 H24 - Module Hardware Description 21
Turning the H24 On Using IGN
The IGN input signal must be set low when not used. To turn on H24, this signal must be asserted
high for at least 8 seconds. The IGN signal must remain high for the duration of the H24
operation. H24 powers down when the IGN signal is returned to its low state.
Figure 2-7: Turning the H24 On Using IGN
Turning the H24 Off
There are several ways to turn the H24 off:
•Asserting the ON_N signal low for a minimum of 2 seconds.
•Setting the IGN signal low.
•Low power automatic shut down.
•AT command.
•Voltage exceeds 4.5V.
•Temperature at PMIC exceeds 125C.
Turning the H24 Off Using ON_N
The ON_N signal is set high using an internal pull up resistor when power is applied to H24.
Asserting the ON_N signal low for a minimum of 2 seconds will turn H24 off. This will initiate a

normal power-off process, which includes disabling of all applications interfaces (SIM card,
audio, etc.) and closing the network connection.
Figure 2-8: Turning the H24 Off Using ON_N
Turning the H24 Off Using IGN
The IGN signal may be used to power off H24 only if it was also used to power it on. When the
IGN signal is set low, H24 will turn off. This will initiate a normal power-off process, which
includes disabling of all applications interfaces (SIM card, audio, etc.) and closing the network
connection.
Figure 2-9: Turning the H24 Off Using IGN
Power Loss shut down
A low power shut down occurs when H24 senses the external power supply is below the minimal
operating limit. The module will respond by powering down automatically without notice.
Chapter 2: Hardware Interface Description
April 15, 2010 H24 - Module Hardware Description 23
This form of power-down is not recommended for regular use since the unexpected power loss
may result in loss of data.
Turning the H24 Off Using AT+MPWRDN
The AT+MPWRDN command initiates a H24 power down (even if the H24 was powered on by
IGN). This command emulates the ON_N signal operation for power off.
Low Power Mode
24 H24 - Module Hardware Description April 15, 2010
Low Power Mode
The H24 incorporates an optional low power mode, called Sleep Mode, in which it operates in
minimum functionality, and therefore draws significantly less current. During low power mode
the H24 network connection is not lost. H24 continues to monitor the GSM network constantly
for any incoming calls or data.
During low power mode, most of the H24 interface signals are inactive and are kept in their
previous state, prior to activating low power mode. To save power, the H24 internal Main clock
and some of its circuits are shut down, and therefore serial communications is limited.
Activating Low Power Mode
UART:
By default, the H24 powers on in Idle mode. In this mode the H24 interfaces and features are
functional and the module is fully active.
Low power mode is controlled by the AT+MSLEEP & ATS24 commands.
The command AT+MSLEEP=1 enable Sleep Mode (AT+MSLEEP=0 disable Sleep Mode).
The value of S24 command determines the inactive state duration required by H24, in seconds,
after which H24 will enter sleep mode.
For example:
ATS24 = 1 activates low power mode after 1 second of UART inactivity.
ATS24 = 5 activates low power mode after 5 seconds of UART inactivity.
Note: ATS24=0 will not disable sleep mode at H24.
AT+MSLEEP = 1 Enable low power mode.
AT+MSLEEP = 0 Disable low power mode (default).
Important: H24 will not enter low power mode in any case when there is data present on the
serial interface.Also when any network (GSM/UMTS ) activity (e.g. incoming
voice call, data session) or an internal system task is running. Only when processing
of any external or internal system task has completed, if AT+MSLEEP=1 and H24
UART is inactive for the duration of ATS24, H24 will enter low power mode.
USB:
Any transaction to the USB will wake up the H24 provided the user USB stack supports
suspend/resume mechanism. In case such mechanism is not supported the user will not be able set
the H24 at sleep mode.
In case of resume event the SW will be responsible to all the needed configurations (endpoints
etc.) to maintain the link. In case the host USB protocols stack doesn't support resume suspend
mechanism the USB module in the H24 will not go to sleep hence the entire H24 will remain
active as long as the USB cable is connected.
Remote wake up is supported.
CTS signal conforms RS-232 standard at this mode.
Chapter 2: Hardware Interface Description
April 15, 2010 H24 - Module Hardware Description 25
Serial Interface During Low Power Mode
During low power mode the H24 serial interfaces are disabled. This is indicated by the CTS_N
signal high state (if hardware flow control is set by AT+IFC=2, 2 (or AT&K4) and CTS control is
set by AT+MSCTS=1 command).
The H24 wakes up periodically from low power mode to listen to paging channel of the
GSM/WCDMA networks for any incoming calls or data. After this short paging is completed,
H24 returns to low power mode. During this short awake period, the serial interfaces are enabled
and communications with the module is possible (if both AT+IFC=2, 2 (or AT&K4) and
AT+MSCTS=1 commands are in use).
The CTS_N signal is alternately enabled and disabled synchronously with the network paging
cycle. CTS_N is enabled whenever H24 awakes to page the network. This indicates the H24
serial interfaces are active (see Figure 2-10).
When using AT+IFC=2, 2 the Terminal should be set to flow control - HW.
When using AT+IFC=0, 0 the Terminal should be set to flow control - None.
Need to disconnect and connect to terminal for the new setup to be active.
RS232 cable hot swap is supported and insert cable will wake up the H24.
WAKEUP_IN line pin 16 (on 70 pin connector) should override any sleep condition and will
prevent H24 from enter sleep mode.
In case user is working with UART and enables HW flow control, it is advised that the user will
plan his system to wake up H24 also using the WAKEUP_IN HW line.
If the following conditions become true the user will be able to wake H24 only through
WAKEUP_IN line (or just return to work with folow control = None); and will not be able to
wake H24 through RX activity (sending data):
•Sleep mode over UART enabled
•UART HW flow control enabled
•Airplane mode enabled (AT+CFUN=0 or AT+CFUN=4).
In this case there is no DRX and CTS is not rising.
Figure 2-10: CTS Signal During Sleep Mode
The periodical enabling and disabling of the CTS_N signal during low power mode can be
controlled by the AT+MSCTS command.
Setting AT+MSCTS=0 permanently disables the serial interface during low power mode, even
during a network page by H24. The CTS_N signal is disabled, and therefore the serial interfaces
are blocked.
Low Power Mode
26 H24 - Module Hardware Description April 15, 2010
Terminating Low Power Mode
Terminating the low power mode, or wake-up, is defined as the transition of the H24 operating
state from Sleep mode to Idle mode. There are several ways (using UART CTS_N signal,
WKUPI_N line or UART RX line interrupt) to wake-up H24 from low power mode as described
below.
Important: During power saving mode the H24 internal clocks and circuits are disabled, in
order to minimize power consumption. When terminating the power saving mode,
and switching to Idle mode, H24 requires a minimal delay time to reactivate and
stabilize its internal circuits before it can respond to application data.
This delay is typically of 100 milliseconds, and is also indicated by the CTS_N
signal inactive (high) state. The delay guarantees that data on the serial interface is
not lost or misinterpreted.
Temporary Termination of Low Power Mode
The WKUPI_N signal is an active low input that is set high by default. By asserting this signal
low the application can wake-up H24 from low power mode and switch to idle mode.
Low power mode may be terminated temporarily by several sources, some of which are user
initiated and others are initiated by the system.
Using the WKUPI_N signal to wake UART from Sleep Mode
The WKUPI_N signal is an active low input, that is set high by default. By asserting this signal
low the application can wake-up H24 from low power mode and switch to Idle mode.
H24 will remain in idle mode, awake and fully active, as long as WKUPI_N signal remains low.
When this signal is disabled and set high again, H24 will return to Sleep mode automatically,
according to the ATS24 settings.
The WKUPI_N signal is the recommended method to temporarily wake-up H24 from low power
mode. It provides the application full control of the H24 operating mode and guarantees that data
on the serial interface will not be lost or misinterpreted.
The WKUPI_N signal can be used to wake up H24 from low power mode. If the serial interface
has been controlled by the AT+IFC=1,1 (or AT&K4) command, the application can work in
Hardware Flow Control accumulate the data in its buffer and send it to the module when the CTS
is Enabled. (Note: this method of operation works without using AT+MSCTS=0 command).
Incoming Network Data
During low power mode, H24 continues monitoring the network (GSM or UMTS) for any
incoming data, message or voice calls.
When H24 receives an indication from the network that an incoming voice call, message or data
is available, it automatically wakes up from low power mode to alert the application. When H24
has completed to process all the tasks related to the incoming data, it will automatically return to
low power mode according to the ATS24 settings.
Depending on the type of network indication and the application settings, H24 may operate in
several methods, which are configurable by AT commands, to alert the application of the
incoming data:
Chapter 2: Hardware Interface Description
April 15, 2010 H24 - Module Hardware Description 27
•Enable the WKUPO_N signal to wake-up the application from low power by setting ATS100
to value bigger then zero. ATS102 can be 0 but is 30ms by default for example ATS102=30
will start WKUPO_N signal 30 millisecond before data send out from UART to Host.
•Send data to the application over the serial interface.
•Enable the serial interface's Ring Indicator (RI_N) signal.
Data on the Serial interface
While H24 is temporarily awake in Idle mode, data may be transmitted on the serial interface. In
case data is being transmitted in any direction, H24 will not return to low power mode. This is
regardless of the original wake-up reason or source. H24 will remain awake while data is
transferred.
Only when the serial interface transfer is completed and the data has been processed, H24 will
return to low power mode automatically, according to the ATS24 settings (see Figure 2-11).
Figure 2-11: Serial Interface Data
UART and USB Exiting of Low Power Mode
Enable/Disable Low Power Mode
The H24 low power mode is enabled and disabled by the AT+MSLEEP command.
To permanently terminate the H24 low power mode, the +MSLEEP=0 command must be used.
H24 will not return to low power mode until an AT+MSLEEP=1 commands is set again.
This command can be sent only when the serial interface is active.
UART Exiting of Low Power Mode
In case the serial interface is disabled, Hardware Flow control is OFF and WKUP_I is not used, it
must first be activated before sending this command. To reactivate the serial interface, a
temporary termination of the low power mode is required, by sending AT command that will
catch by the RX line interrupt service routine and will use to wake up the module (The execution
of the first command after exit Sleep Mode by RX interrupt is not guarantied.
USB Exiting of Low Power Mode
Handled by suspend/resume mechanism.
Real Time Clock
28 H24 - Module Hardware Description April 15, 2010
Real Time Clock
H24 incorporates a Real Time Clock (RTC) mechanism that performs time keeping. The RTC
subsystem is embedded in the PMIC and operates in all of the H24 operating modes (Off, Idle,
Sleep), as long as power is supplied above the minimum operating level.
The H24 time and date can be set using the following methods:
•Automatically retrieved from the GSM network.
In case H24 is operated in a GSM network that supports automatic time zone updating, it will
update the RTC with the local time and date upon connection to the network. The RTC will
continue to keep the time from that point.
•Using the AT+CCLK command.
Setting the time and date manually by this AT commands overrides the automatic network
update.
Once the time and date are manually updated, the RTC timer will keep the time and date
synchronized regardless of the H24 operating state.
When the power supply is disconnected from H24, the RTC timer will reset and the current time
and date will be lost. On the next H24 power-up the time and date will need to be set again
automatically or manually.
Nevertheless, there is ability to keep the RTC working while main power supply is off.
This can be done by supplying the RTC an external power of 3V to a dedicated pin in the
microprocessor.
This dedicated pin is called Vcoin.
When the main power supply is off and Vcoin is active, the RTC is still working.
When power supply is off, no Vcoin applied, the RTC will work only for 2 sec, and will turn
"off".

April 15, 2010 H24 - Module Hardware Description 29
Serial Interfaces
H24 includes three completely independent serial communications interfaces, which may be used
by the application for several purposes.
Primary UART (UART1)
The H24 primary UART is a standard 8-signal bus. The primary UART is used for all the
communications with H24 - AT commands interface, GPRS/EGPRS data and CSD data,
programming and software upgrades.
The UART signals are active low CMOS level signals. For standard RS232 communications with
a PC, an external transceiver is required.
H24 is defined as a DCE device, and the user application is defined as the DTE device. These
definitions apply for the UART signals naming conventions, and the direction of data flow, as
described in Figure 2-12.
Figure 2-12: UART1 Interface Signals
The H24 primary UART supports maximum data rate of up to 4 Mbps interface and up to 230
kbps for data services using the UART1 interface.
All flow control handshakes are supported: hardware, software, or none.
Parity bit and Stop bit definitions are also supported.
The UART default port configuration is 8 data bits, 1 stop bit and no parity, with hardware flow
control.
USB Interface
H24 incorporates a standard Universal Serial Bus (USB) interface.
The H24 USB electrical interface and protocol conform to the USB 2.0 high-speed specifications.
H24 is defined as a USB device on the USB bus and does not support hub or host functionality.
Serial Interfaces
30 H24 - Module Hardware Description April 15, 2010
USB may be used for standard communications with H24, as done through the UART interface.
The USB interface signals are shown in Figure 2-13.
Figure 2-13: USB Interface Signals
UID determines the USB mode configuration: Host or Client (Client mode is supported).
Note: Do not connect USB_ID pin (pin 45).
Important: When layouting USB signals: Run HS_D_P/M as diff pair with equal length , to
maintain a nominal 90 Ω differential impedance +/-15%, single-ended impedance in
a range of 42 to 78 Ω being acceptable.
Chapter 2: Hardware Interface Description
April 15, 2010 H24 - Module Hardware Description 31
SIM Interface
The H24 incorporates a SIM interface, which conforms to the GSM 11.11 and GSM 11.12
standards, that are based on the ISO/IEC 7816 standard. These standards define the electrical,
signaling and protocol specifications of a GSM SIM card.
H24 does not incorporate an on-board SIM card tray for SIM placement. The SIM must be
located on the user application board, external to the H24. The H24 SIM interface includes all the
necessary signals, which are routed to the interface connector, for a direct and complete
connection to an external SIM.
H24 supports dynamic detection of the SIM card, through a dedicated SIM detection signal. H24
will detect a SIM card insertion or removal upon power up or during operation by the transitions
on the SIM_PD_N signal.
Some of the H24 models incorporates eSIM (embedded SIM). Refer to “Embedded SIM” on
page 32.
External SIM Connection
Table 2-5 details the SIM interface signals.
SIM Design Guidelines
The SIM interface and signals design is extremely important for proper operation of H24 and the
SIM card. There are several design guidelines that must be followed to achieve a robust and
stable design that meets the required standards and regulations.
•Using the SIM detection signal, SIM_PD_N, is mandatory in case the SIM card is accessible
to the user and may be removed during H24 operation. To avoid any damage to the SIM or
H24, the SIM interface signals must be deactivated before the SIM card contacts are
mechanically removed from the SIM tray contacts. Therefore, the SIM_PD_N detection
signal must be disabled before the SIM is removed from its tray.
•The SIM should be located, and its signals should be routed, away from any possible EMI
sources, such as the RF antenna and digital switching signals.
•The SIM interface signals length should not exceed 100 mm between the H24 interface
connector and the SIM tray. This is to meet with EMC regulations and improve signal
integrity.

•To avoid crosstalk between the SIM clock and data signals (SIM_CLK and SIM_DIO), it is
recommended to rout them separately on the application board, and preferably isolated by a
surrounding ground plane.
•The SIM card signals should be protected from ESD using very low capacitance protective
elements (zener diodes, etc.).
•The H24 interface does not support SIM programming through the VPP signal. This signal
should not be connected to H24.
•SIM voltage level will not drop below 2.7V (1.6V for 1.8V SIM card) during hot insertion.
•It is recommended to add series termination at signals SIM CLK (100 Ohm) and the
SIM_DIO (56 Ohm) and bypass SIM_VCC with a 100nF cap.
Embedded SIM
The H24 newest feature is incorporating an Embedded SIM inside (depending on H24 model).
Embedded SIM (e.g. eSIM or chip SIM), is a secured micro controller IC, with the same pinout
interface, and the same operation as an external SIM card.
The eSIM main advantage is it robustness, making it an ideal solution for M2M applications.
Since an eSIM is actually an IC soldered on the H24, it can withstand wider temperature range
then a regular external SIM card that is usually made of plastic, and gets twisted and bowed at
high temperature, causing disconnection inside the SIM tray.
For the same reason, the eSIM is more durable to vibration then a regular external SIM card. Hard
vibration on an application with a SIM card socket may result in with an intermitted connection
between the SIM card socket and the SIM card.
Two signals are associated with the eSIM:
•SIM_PD_N: (pin 50) This signal must be set low for acknowledge the H24 that eSIM is
connected.
•Chip SIM reset: (pin 56) This pin is dedicated for reseting the eSIM. In case that the eSIM is
incorporated, short circuit this pin to pin 44 (SIM_RST_N).

The output power for the differential EAR1 output is typically 70 mW for a full-scale +3 dBm0
sine wave into a 32Ω speaker.
Both microphone pins require 2.2 k bias resistors and 0.1µF AC-coupling capacitors.
The positive microphone terminal is connected to the µC MICBIAS pin through one of the
2.2 kΩ resistors; this 1.8 V output provides 1 mA of bias current for the Microphone.
MICBIAS supports multiple microphones simultaneously up to 1 mA.
In case the user connect single-ended mic, he must connect it to pin 61 and short circuit pin 62 to

Audio Design
The audio quality delivered by H24 is highly affected by the application audio design,
particularly when using the analog audio interface. Therefore, special care must be taken when
designing the H24 audio interface. Improper design and implementation of the audio interface
will result in poor audio quality.
Poor audio quality is a result of electrical interferences, or noises, from circuits surrounding the
audio interface. There are several possible sources for the audio noise:
•Transients and losses on the power supply
•EMI from antenna radiations
•Digital logic switching noise
Most of the audio noise originates from the GSM transmit burst current surges (217 Hz TDMA
buzz), which appear on the main power supply lines and antenna, but also indirectly penetrate the
internal application's supplies and signals. The noises are transferred into the H24's audio circuits
through the microphone input signals and then are amplified by the H24's internal audio
amplifiers.
To minimize the audio noise and improve the audio performance the microphone and speaker
signals must be designed with sufficient protection from surrounding noises.
The following guidelines should be followed to achieve best audio performance:
•Reference the microphone input circuits to the H24 AGND interface signal.
•If using single-ended audio outputs, they should be referenced to the H24 AGND interface
signal.
•Keep the audio circuits away from the antenna.
•Use RF filtering capacitors on the audio signals, as described in Table 2-3.

•The audio signals should not be routed adjacent to digital signals.
•Isolate the audio signals by a surrounding ground plane or shields.
•Filter internal supplies and signals that may indirectly affect the audio circuits, from noises
and voltage drops.
Analog Ground
The H24 interface incorporates a dedicated analog ground contact, AGND pin 59, which is
internally connected to the H24's ground. The AGND signal is intended to provide a separate
ground connection for the application's external audio devices and circuits.
This signal provides an isolated ground connection directly from H24, which is separated from
the noisy digital ground of the application. It is recommended to connect this signal to analog
audio devices and circuits used by the application. Using a separate analog ground minimizes
audio noises and improves the audio circuit's immunity from external interferences.
Digital Audio Interface
The H24 digital audio interface is a serial Pulse Code Modulation (PCM) bus, which uses linear
2's compliment coding. H24 is the PCM bus master, supplying the clock and sync signals to the
application.
The H24 digital interface is a 4 signal PCM bus, which includes a bit clock output signal for the
bus timing, a frame sync output signal for audio sampling timing, and serial data input and output
signals.
Important: The PCM bus signals are shared internally by the analog audio interface and the
digital audio interface. Therefore, when using the analog audio interface the PCM
bus signals must be tri-stated or disconnected at the interface connector.
The digital audio interface supports 4 types of audio data formats, which define the PCM bus
configuration and data rates:
•Voice band audio - Intended for speech during voice calls and for mono rings and alerts.
•Stereo audio - Includes 3 audio formats that support high quality stereo ring tones and alerts.
Voiceband Audio
This digital voice audio format is used for speech during voice calls and for mono rings and
alerts.
The PCM bus signal's configuration for voiceband audio is:
•PCM_CLK - 2048 kHz serial clock
•PCM_FS - 8 kHz bit-wide frame-sync
•PCM_DOUT - 13-bit linear audio data output
•PCM_DIN - 13-bit linear audio data input
The analog audio is sampled at an 8 kHz rate and converted to linear 13-bit serial PCM audio
data. The serial data is transferred on the PCM bus in 16-bit word format, which includes 13
sampled data bits, and 3 added zero value bits.
Audio Interface
38 H24 - Module Hardware Description April 15, 2010
The 16-bit serial data is transferred in both directions after each sync signal's falling edge. The
sync signal pulse duration is one clock period, after which the serial data is transferred in both
directions for 16 consecutive clock periods.
Following the 16-bit data transfer, the serial input and output data signals inactivate until the next
sync pulse, which occurs every 125 µS (8 kHz). It is recommended the serial data signals will be
High-Z during the inactive period.
Important: In digital audio mode the input and output gains cannot be controlled by AT
commands.
Figure 2-18 illustrates the PCM bus format of the voiceband audio configuration.

Chapter 2: Hardware Interface Description
April 15, 2010 H24 - Module Hardware Description 39
Controls and Indicators Interface
The H24 incorporates several interface signals for controlling and monitoring the module's
operation. The following paragraphs describes these signals and their operation.
Table 2-6 gives a description of the controls and indicators signals.
Reset
The RESET_N output signal indicates the H24's operating status. This signal is set high after
power up, when H24 is operating. It is set low when H24 is powered off.
When the RESET_N signal is low, the H24 interface signals are disabled and do not represent any
valid data or state. Furthermore, any input signals connected to the H24 interface must be
disabled (tri-state) or set low when RESET_N is low.
VREF Reference Regulator
The H24 incorporates a regulated voltage output, VREF. The regulator provides a 2.6V output for
use by the customer application. This regulator can source up to 300 mA of current to power any
external digital circuits.
Important: The VREF regulator is powered from the H24's main power supply, and therefore
any current sourced through this regulator originates from the H24 VCC supply.
The overall VCC current consumed by H24 is directly affected by the VREF
operation. The H24 current consumption rises with respect to the current sourced
through VREF.
The VREF regulator incorporates 3 operating modes that are controlled by the AT+MVREF
command. These modes define the regulator operating state relative to the H24's operating mode.

OFF Mode
In this mode the VREF regulator is disabled and its output drops to 0V, regardless of the H24
operating state.
Sleep Mode
The 300 mA rated linear regulator offers a low power mode to reduce its quiescent current during
the module’s sleep mode. This mode uses reduced current in the feedback loop, causing degraded
performance (PSRR, output current capability, etc.). In fact, if the load increases beyond 1 mA
the output voltage can go out of specification. This mode should only be used when the module is
in its sleep mode.
Active Mode
In this mode the VREF regulator is always fully active while H24 is operating, regardless of the
H24 operating mode.
Table 2-7 gives the VREF specifications.
Wakeup Out
Some applications incorporate their own power saving mode, in which they operate with minimal
functionality, including disabling of interfaces and serial communications.
The wakeup-out (WKUPO_N) signal is an active low output, which is designed to support a low
power mode feature in the host application. This signal is used by H24 to indicate that it requires
to communicate with the host application through the serial interface, due to an incoming call or
data, or an unsolicited event. Applications that incorporate a low power mode should use this
signal as an indication to switch from low power mode to normal operation, and activate the serial
interface.
The wakeup-out mechanism, using the WKUPO_N signal, is controlled by 2 AT commands (see
Figure 2-19):
•ATS102 - Defines the delay time in milliseconds that H24 will wait, after asserting the
WKUPO_N signal low, before sending data on the serial interface. This delay is required to
allow the application enough time to reactivate from low power mode and switch to normal

mode.
If ATS102=0, which is the default value, the WKUPO_N signal and mechanism is disabled.
In case the serial interface incorporates hardware flow control signals, the data will be sent
according to their state, after the ATS102 delay time has expired.
•ATS100 - Defines the application minimal wakeup duration, in seconds, for a single wakeup
event. This time definition is required to avoid frequent unnecessary wakeup events and
consequent ATS102 delays.
The application may return to low power mode after the serial interface has been inactive for
the duration set by ATS100. This duration is measured from the last data sent or received on
the serial interface.
Figure 2-19: WKUPO_N Operation
The following guidelines apply to the wakeup-out mechanism:
•H24 will set the WKUPO_N signal low to indicate that in has data to send through the serial
interface.
•H24 will start sending the data to the application after the delay defined by ATS102.
•The WKUPO_N signal will remain low while data is being sent to the host application.
•The host application should keep its serial interface active, and not switch to low power
mode, while the WKUPO_N signal is low.
•H24 will set the WKUPO_N signal high when it has completed sending the data.
•The application serial interface must stay active, and not switch to low power mode, for the
duration set by ATS100, after WKUPO_N is set high.
•H24 will not set the WKUPO_N signal low if it needs to send additional data during the
ATS100 delay time.
•The application may switch to low power mode after the WKUPO_N signal is set high and
the serial interface has been inactive for the duration set by ATS100.
Network Connection Detection
The network connection output signal (Pin 49) indicates the network (GPRS/EGPRS or
WCDMA/HSPA) connection status. When H24 is connected to a network, this signal is enabled.
When H24 is not connected to the GPRS/EGPRS or WCDMA/HSPA network this signal is
disabled. This pin (Pin 49) is enabled by the command AT+MCWAKE.
Controls and Indicators Interface
42 H24 - Module Hardware Description April 15, 2010
Transmission Indicator
The TXEN_N output signal indicates when H24 is transmitting over the GSM or CDMA
network. This signal follows the H24 GSM transmit bursts. This signal is set low during
transmission burst, and set high when no transmission is in progress.
Figure 2-20 shows the TXEN_N operation.
Figure 2-20: TXEN_N Operation
General Purpose I/O
The H24 incorporates 8 general purpose IO signals for the user application. Each GPIO signal
may be configured and controlled by AT command. These signals may be used to control or set
external application circuits, or to receive indications from the external application.

Antenna Interface
The H24 antenna connector is the RF interface to the GSM/WCDMA network.
The antenna interface is terminated by an MMCX connector type, which is 50Ω impedance
matched at the relevant GSM/WCDMA frequencies.
The antenna or antenna application must be installed properly to achieve best performance.
Table 2-8 gives the antenna interface specifications.
It is the Integrator's responsibility to design the antenna or antenna assembly used with the H24.
This will highly affect the RF performance of the H24 (dropped calls, battery consumption etc.).
The following guidelines should be followed:
•Make sure that the antenna or antenna assembly matches the Antenna Interface
Specifications.
•Use low loss RF cable and connectors keeping cable runs to a minimum.

Diversity
RX Diversity Overview
The usage of diversity antenna has a great advantage of improving receiver sensitivity.
H24 HSPA series offers antenna diversity feature to be used in the UMTS/HSPA frequency
bands.
The receiver sensitivity improvement is achieved by:
•Fading effect improvement
While one antenna is in fade, the other antenna is probably not.
•Better Noise Figure
Two antennas will receive more signal power then one antenna and while combining two
signals the uncorrelated noise will be reduced.
•Interference rejection
Combining the received signal with weighting selected so that correlated interfering signals
picked up on both antennas tend to cancel each other out.
Performance
Typical 4dB sensitivity improvement is shown while the H24 is in conducted lab conditions:
Base station is connected with RF cables to both RX main port and RX diversity port due to
diversity port usage (measured in all H24 UMTS supported bands).
Diversity antenna requirements
•Diversity Rx-Only antenna - typically smaller than the primary antenna.
•Antenna should be designed for the supported UMTS/HSPA bands of interest.
•UMTS/HSPA RX frequencies:
•Antenna impedance - 50Ohm.
•Free space antenna efficiency should be greater than -7 dB (20%).
•Antenna VSWR < 3:1 in free space for all bands.
•Delta gain between primary and secondary antennas should be greater than -3 dB.
•Isolation from primary antenna to secondary antenna should be greater than 8 dB.

Diversity Antenna Design Recommendations
•For better Isolation it is recommended to increase distance between primary antenna and
secondary antenna as possible.
•For lower antenna correlation (lower correlation improves performance under fading
conditions) it is recommended that diversity antenna polarity will be horizontal in case main
antenna is vertical.
•It is important to complete TRP and TIS testing at the chamber include both primary and
diversity antenna installed. These tests are typically required by the network operators as part
of their acceptance requirements.

H24 Mounting
64 H24 - Module Hardware Description April 15, 2010
H24 Mounting
The H24 incorporates 2 mechanical holes for installing the module onto the application board.
The holes are 2.4 millimeters in diameter, which accommodates several types of mechanical
elements.
Several mechanical approaches may be applied to mount and fasten H24 to the application board.
Using M2 screws with suitable washers to mount the module onto spacers, a bracket or chassis is
a recommended design.
Special attention must be paid to the area surrounding the H24 mounting holes. A grounding pad
of 4.4 millimeters in diameter surrounds these holes. The diameter and area of this pad must not
be exceeded by any mechanical or electrical element. Several electrical components, which are
not shielded, are located near the holes. These components must not be in contact with the
mounting elements or with other parts of the application board, and care must be taken to avoid
any damage.
Figure 4-8 depicts the H24 mounting area.
Figure 4-8: H24 Mounting Area
The holes are used for mechanical mounting of H24 to the application board but also for
grounding support. Using conductive elements to install H24, significantly improves the overall
grounding of the module and therefore improves the H24 performance and stability.
It is required to use screws or other mechanical elements to fasten H24 to the application board,
but it is highly recommended to use conductive elements to improve the module's performance.
The preferred mounting screw head types are:
• "Allen" head with a champer - the best choice.
• "Star" head - good.
• "Philips" head - may cause damage to nearby components.
