Chapter 2: Hardware Interface Description March 31, 2008 Module Hardware Description 9Operating ModesW24 incorporates several operating modes. Each operating mode is different in the active features and interfaces.Table 2-1 summarizes the general characteristics of the W24 operating modes and provides general guidelines for operation.Table 2-1: W24 Operating Modes Mode Description FeaturesNot Powered VCC supply is disconnected. The W24 is Off.Any signals connected to the interface con-nector must be set low or tri-state.Powered off Valid VCC supply. All W24 voltage regula-tors are disabled.The W24 Interfaces and circuits are powered down. Only the power up/down control cir-cuit is monitoring the IGN and ON_N sig-nals. Any signals connected to the interface connector must be set low or tri-stated.Off-mode Valid VCC supply. W24 powered down by ON_N, while IGN set high. All W24 voltage regulators are active.The W24 Interfaces and circuits are powered down. The CPU is running at 32kHz and monitoring IGN and ON_N signals. Any sig-nals connected to the interface connector must be set low or tri-stated.Sleep RESET_N signal is high.CTS_N signal is disabled.The W24 is in low power mode.The application interfaces are disabled, but, W24 continues to monitor the Wi-Fi network.Deep Sleep RESET_N signal is high.CTS_N signal is disabled.The W24 enters deep sleep mode if it cannot find an AP that it can register to. It wakes up periodically to rescan and try to register. If the AP is found, it exits the deep sleep mode. If the AP cannot be found/registered to, it goes back to deep sleep mode - during that time it disables the RF section and does not monitor the Wi-Fi network.Idle RESET_N signal is disabled (high).CTS_N and DSR_N signals are enabled (low).The W24 is fully active, connected to the Wi-Fi network and ready to communicate.This is the default power-up mode.Airplane RF block disabled. The W24 interfaces are fully active, but its RF section is disabled.Tx RESET_N signal is high.TXEN_N signal is toggling.A Wi-Fi data transmission is in progress. When data transmission terminates, W24 returns to the last operating state (Idle or Sleep).
Power Supply10 Module Hardware Description March 31, 2008Power SupplyThe W24 power supply must be a single external DC voltage source of 3.3V to 4.2V. In order to support the stacked configuration, i.e. when G24 cellular module is coupled on the W24 module, the power supply must be able to sustain the required voltage level during a GSM transmit burst current surge, which may reach 2.0A.The W24 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.Power Supply DesignNote: The power design conciderations show maximum requirements for stacked configuration.Special care must be taken when designing the power supply of the W24 in stacked configuration. The single external DC power source indirectly supplies all the digital and analog interfaces, but also directly supplies the G24 RF power amplifier (PA). Therefore, any degradation in the power supply performance, due to losses, noises or transients, will directly affect the G24 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 W24 and G24 performance.Table 2-2: Power Supply SignalsPin # Signal Name Description1-4 GND Main ground connection for W24 module.5-8 VCC DC supply input for W24 module.VIN = 3.3 V to 4.2 VIRMS = 250 mA during transmis-sion (Stand alone)IRMS = 900 mA during multi-slot transmission (with G24)IMAX = 2.5 A during transmit bursts

Power On/Off Operation12 Module Hardware Description March 31, 2008Power On/Off OperationThe W24 power on consists of two primary phases:Initial power up is hardware controlled by the Power-up/down circuit which monitors two power-up control signals: ON_N and IGN. If any of these two signals is asserted, the Power-up/down circuit will enable Voltage regulators and the power management IC. They will provide valid supply voltages to the processor which will start to boot.The second phase is SW controlled. Processor checks the state of ON_N and IGN signals and if any of them is asserted, the CPU takes control over the voltage regulators and power management IC and holds them enabled.Power down is controlled by SW - Once valid power-down condition occurs, CPU will release the signal which keeps the regulators and power management enabled, thus causing the W24 to power down. If this happened while IGN signal is still asserted, the regulators will remain active, and the unit will enter "Off mode".W24 state is indicated at the interface connector by the hardware output signals RESET_N. The RESET_N signal indicates whether W24 is powered on or off. When the RESET_N is low, W24 is powered-off. When it is high, W24 is powered-on.Important: Do not operate the W24 out of its electrical or environmental limits. Refer to the specifications chapter for details of these limits.Turning the W24 OnWhen the W24 power supply is stable above the minimum operating level and W24 is powered off, all of its circuits are disabled.When W24 is turned on, by any of the methods described below, it will first perform an automatic initialization. When the initialization has completed, W24 resumes normal operation (stand alone mode), or turns on the G24 module (stacked modules) and resumes normal operation.During the internal system-test process W24 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.Valid Turn-on reasons are:•ON_N asserted low for 0.5s•IGNITION assertedNote: During FW upgrades (reflashing) make sure to power-up the W24 by IGN.Turning the W24 On Using ON_NThe ON_N input signal is set high by an internal pull-up resistor whenever a power supply is applied to W24. 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 W24 to turn-on.
Chapter 2: Hardware Interface Description March 31, 2008 Module Hardware Description 13Asserting the ON_N signal low for more than 1.5 seconds may cause the W24 to interpret the signal as a power-off command, and turn off immediately after turning on.Figure 2-3 illustrates the power-on process using the ON_N signal.Figure 2-3: ON_N Power On TimingTurning the W24 On Using IGNThe IGN input signal must be set low when not used. To turn on W24, this signal must be asserted high. The IGN signal must remain high for the duration of the W24 operation. W24 powers down when the IGN signal is returned to its low state.Important: It is recommended to place a pull-down resistor in the customer application, on the IGN signal. A 100 kohm resistor, or less, is acceptable.Figure 2-4 illustrates the power-on process using the IGN signal.Figure 2-4: IGN Power On Timing
Power On/Off Operation14 Module Hardware Description March 31, 2008Turning the W24 OffThere are several ways to turn the W24 off:•Asserting the ON_N signal low for a minimum of 2 seconds.•Setting the IGN signal low.•Turning the W24 Off using AT+iMRST.Note: If the unit was powered up by ON_N signal, W24 will ignore attempt to turn it off by setting the IGNITION to low.Turning the W24 Off Using ON_NThe ON_N signal is internally pulled-up when power is applied to W24.Asserting the ON_N signal low for a minimum of 2 seconds will turn W24 off. This will initiate a normal power-off process, which includes G24 power down (stacked configuration) and disabling of all applications interfaces (UART, USB, etc.).Figure 2-5 illustrates the power-off timings when using the ON_N signal.Figure 2-5: ON_N Power Off TimingNote: If the unit was powered up by IGN, and it's being turned off by ON_N, the unit will enter "Off mode", and not power off.Turning the W24 Off Using IGNThe IGN signal may be used to power off W24 if the unit was powered-up by the IGN signal. When the IGN signal is set low, W24 will turn off. This will initiate a normal power-off process, which includes G24 power down (stacked configuration) and disabling of all applications interfaces (UART, USB, etc.).The IGN signal will not power off W24 before 30 seconds have elapsed since W24 was powered-on. This delay mechanism is implemented to protect W24 from unexpected transients on the IGN line during power up, particularly when applying vehicle cranking waveforms.
Chapter 2: Hardware Interface Description March 31, 2008 Module Hardware Description 15Figure 2-6 illustrates the power-off timings when using the IGN signal.Figure 2-6: IGN Power Off TimingPower Loss shut downA low power shut down occurs when W24 senses that the external power supply is below the minimal operating limit. The module will respond by powering down automatically without notice.This form of power-down is not recommended for regular use since the unexpected power loss may result in loss of data.Turning the W24 Off Using AT+iMRSTThe AT+iMRST command initiates a W24 system reset operation, which powers off the W24. This command emulates the ON_N signal operation for W24 power off.Note: In Stacked configuration, AT+iMRST powers down W24 only. It does not power down the G24 or any similar module.
Low Power Mode16 Module Hardware Description March 31, 2008Low Power ModeThe W24 supports optional low power modes, called Sleep Mode and Deep Sleep Mode, in which it operates with minimum functionality, and therefore draws significantly less current. During Sleep Mode the W24 network connection is not lost. W24 continues to monitor the network constantly for any incoming data.During low power mode, all of the W24 interface signals are inactive and are kept in their previous state, prior to activating low power mode. To save power, all the W24 internal clocks and circuits are shut down, and therefore serial communications are disabled.In the cases where no Access Point can be found at W24 power-up, W24 will enter Deep Sleep Mode. During Deep Sleep Mode, network connection does not exist. W24 will periodically come out of Deep Sleep Mode, to attempt to locate APs. If the search is not successful, the module will return to Deep Sleep Mode.Activating Low Power ModeBy default, the W24 powers on in Idle mode. In this mode, all the W24 interfaces and features are functional and the module is fully active. Sleep mode is activated by setting the AT+iPSE>0.When the WAKEUP_N signal is disabled (high) and no data is present on the serial interface or incoming from the Wi-Fi network, and no internal system task is running, W24 will enter Sleep mode.When in Sleep mode, the W24 disables all its serial interfaces (USB and UARTs), and the VBUS output signal of the cellular connector (stacked configuration).The W24 continues to respond to both external and internal interrupts.The following conditions must be met for the W24 to enter Sleep mode:•WKUPI_N signal is disabled (high).•AT+ iPSE and AT+ iS102 parameter values are not 0.•For example:•AT+ iPSE = 1 activates low power mode after 1 second of inactivity.•AT+ iPSE = 5 activates low power mode after 5 seconds of inactivity.•AT+ iPSE = 0 disables low power mode (default).•AT+ iWLPS parameter value is not 0, so the Wi-Fi chip is in automatic power save mode.•No host command in currently being processed.•No WPA process is currently active. For example, scanning or handshake.•Carrier lost handling is not in process.•No data is waiting to be transmitted over any of the active sockets.•No data is waiting to be sent in SerialNET mode.For more information about AT+ iS100 and AT+ iS102 parameters, see the following sections.Important: W24 will not enter Sleep mode in any case when data is present on the serial interface or incoming from the Wi-Fi network, or an internal system task is running. Only when processing of a pending external or internal system task has completed, W24 will enter Sleep mode according to the AT+iPSE command settings.
Chapter 2: Hardware Interface Description March 31, 2008 Module Hardware Description 17Serial Interface During Low Power ModeDuring low power mode the W24 serial interfaces are disabled.The W24 wakes up periodically from low power mode to monitor the network for data. After this short paging is completed, W24 returns to low power mode. During this short awake period, the serial interfaces are enabled and communications with the module is possible.Terminating Low Power ModeTo bring W24 back from the sleep mode, WAKEUP_N needs to be asserted (set low). The W24 Sleep mode is enabled or disabled by the AT+iPSE command. To permanently terminate the W24 Sleep mode, the AT+iPSE=0 command is used. W24 does not enter Sleep mode until an AT+iPSE>0 command is sent.Important: During power save mode the W24 internal clocks and circuits are disabled, in order to minimize power consumption. When terminating the power saving mode, and switching to Idle mode, W24 requires a minimal delay time to reactivate and stabilize its internal circuits before it can respond to application data. This delay is typically 5 milliseconds. The delay guarantees that data on the serial interface is not lost or misinterpreted.Temporary Termination of Low Power ModeTemporary termination of low power mode occurs when W24 switches from Sleep mode to Idle mode for a defined period, and then returns automatically to Sleep 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 signalThe WKUPI_N signal is an active low input, that is set high by default. By asserting this signal low the application can wake-up W24 from low power mode and switch to Idle mode.W24 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, W24 will return to Sleep mode automatically, according to the AT+iPSE settings (see Figure 2-7).Figure 2-7: WKUPI_N Signal Operation
Low Power Mode18 Module Hardware Description March 31, 2008The WKUPI_N signal is the recommended method to temporarily wake-up W24 from low power mode. It provides the application full control of the W24 operating mode and guarantees that data on the serial interface will not be lost or misinterpreted.Using the WKUPO_N signalThe WKUPO_N signal is an active-low W24 output that is asserted high by default. By asserting this signal low, the host can be waked up by W24. WKUPO_N alerts the host that W24 exits from Sleep mode into Idle mode due to network activity (see Figure 2-8).Figure 2-8: WKUPO_N Signal OperationThe AT+iS102 parameter defines the delay time, in milliseconds, that W24 waits when in SerialNET mode, after asserting the WKUPO_N signal, and before sending data on the host interface. This delay is required to allow the application enough time to re-activate from low power mode and switch to normal mode. If S102=0, which is the default value, the WKUPO_N signal and mechanism is disabled. In other words, W24 will never assert the WKUPO_N signal. AT+iS100 defines the minimal time interval, in milliseconds, that W24 waits before asserting WKUPO_N after de-asserting it. In other words, W24 will not assert the WKUPO_N signal if the time that had passed from the previous de-assertion of this signal is not at least the duration specified by the S100 parameter. This time interval is required to avoid frequent unnecessary wakeup events and consequent S102 delays. The S100 parameter is relevant only if S102>0, which enables the WKUPO_N signal operation. Incoming Network DataDuring low power mode, W24 continues monitoring the Wi-Fi network for any incoming data.When W24 receives an indication from the network that data is available, it automatically wakes up from low power mode to alert the application. When W24 has completed to process all the tasks related to the incoming data, it will automatically return to low power mode according to the AT+iEPS settings.Depending on the type of network indication and the application settings, W24 may operate in several methods, which are configurable by AT commands, to alert the application of the incoming data:•Enable the WKUPO_N signal to wake-up the application from low power.•Send data to the application over the serial interface.Data on the Serial interfaceWhile W24 is temporarily awake in Idle mode, data may be transmitted on the serial interface. In case data is being transmitted in any direction, W24 will not return to low power mode. This is
Chapter 2: Hardware Interface Description March 31, 2008 Module Hardware Description 19regardless of the original wake-up reason or source. W24 will remain awake while data is transferred.Only when the serial interface transfer is completed and the data has been processed, W24 will return to low power mode automatically, according to the AT+iPSE settings (see Figure 2-9).Figure 2-9: Serial Interface DataPermanent termination of Low Power ModeThe W24 low power mode is enabled and disabled by the AT+iPSE command.To permanently terminate the W24 low power mode, the AT+iPSE = 0 command must be used. Setting AT+iPSE = 0 disables the currently active low power mode and switches W24 to Idle mode.W24 will not return to low power mode until an AT+iPSE > 0 commands is set again.This command can be sent only when the serial interface is active.In case the serial interface is disabled, it must first be activated before sending this command. To reactivate the serial interface, a temporary termination of the low power mode is required, as described in “Temporary Termination of Low Power Mode” on page 17.Following the temporary low power mode termination, the serial interface will activate and the AT+iPSE = 0 command can be received by W24.Deep Sleep ModeIn case that W24 cannot locate an active access point or cannot register to it, W24 will enter the Deep Sleep Mode.During Deep Sleep Mode, network connection does not exist. W24 will periodically come out of the Deep Sleep Mode, to attempt to locate APs. If the search is not successful, the module will return to the Deep Sleep Mode.The time between consecutive attempts to locate an AP is set by the AT+iWLSI command.
Serial Interfaces20 Module Hardware Description March 31, 2008Serial InterfacesW24 includes three completely independent serial communications interfaces, which may be used by the application for several purposes (see Figure 2-10).Figure 2-10: Serial Interfaces Block DiagramPrimary UART (UART1)The W24 primary UART is a standard 8-signal bus. The primary UART is used for all the communications with W24 - AT+i commands interface, Wi-Fi data, and G24- AT command Interface (stacked configuration), 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.W24 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 2-11.Figure 2-11: UART1 Interface Signals
Chapter 2: Hardware Interface Description March 31, 2008 Module Hardware Description 21The W24 primary UART supports baud rates 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, as well as the extended high speed rates: 1Mbps, 1.5Mbps and 3Mbps. Auto baud rate detection is supported for baud rates up to 115200 bps. 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 and auto baud rate detect enabled.Primary UART is defined for 3 different HW models: standard, stand alone and JAVA models.In the standard model, Primary UART is connected directly to W24 processor. 'AT+i' standard command will be executed by the W24, while 'AT' commands that are for the G24 primary UART (stacked configuration), will be diverted by the W24 processor to the G24 interface connector, and will be executed by the G24.In the JAVA model, where the G24 JAVA model function as W24 Host application, all UART commands will be diverted to the G24 interface connector (by different HW wiring), and the G24 will execute them.Important: The W24 UART will not send data over the serial interface in case the DTR_N and/or RTS_N input signals are disabled (set high). Therefore, regardless of the handshake method, it is still required to enable these signals for proper operation, by asserting them low.Note: Add a pull-up resistors (22-100K) on all UART input signals that can be left in an undefined state (Hi-Z). The resistors should pull to the VREF voltage level.Secondary UART (UART2)W24 incorporates Secondary UART interface intended to support G24 UART2 interface, in stacked configuration. The interface consists of the following pins (see Table 2-4):The above signals are routed from 70-pin host connector to G24 70-pin connector via W24. They are not internally connected to W24 circuits. If the W24 will be used as stand alone only, the above pins should be left open.For more details on implementing a secondary interface for use with G24, please refer to the "Motorola G24 Developer's Guide - Module Hardware Description", PN 6889192V27.Table 2-4: Secondary UART Interface SignalsPin # Pin Name Description29 RXD2 Receive Data31 TXD2 Transmit Data33 RTS2 Request To Send35 CTS2 Clear To Send
Serial Interfaces22 Module Hardware Description March 31, 2008USB Device InterfaceW24 incorporates a standard Universal Serial Bus (USB) interface.The interface consists of the following pins (see Table 2-5):The W24 USB electrical interface and protocol conform to the USB 2.0 full-speed specifications. W24 is defined as a USB device on the 70-pin Host Connector. This interface does not support hub or host functionality.USB may be used for standard communications with W24, as done through the UART interface.USB Host Interface (Stacked configuration only)W24 incorporates USB Host interface intended to support G24 USB interface, in stacked configuration.

Chapter 2: Hardware Interface Description March 31, 2008 Module Hardware Description 27Controls and Indicators InterfaceThe W24 incorporates several interface signals for controlling and monitoring the module's operation. The following paragraphs describes these signals and their operation.Table 2-12 gives a description of the controls and indicators signals.ResetThe RESET_N output signal indicates the W24's operating status. This signal is set high after power up, when W24 is operating. It is set low when W24 is powered off.When the RESET_N signal is low, the W24 interface signals are disabled and do not represent any valid data or state. Furthermore, any input signals connected to the W24 interface must be disabled (tri-state) or set low when RESET_N is low.VREF Reference RegulatorThe W24 incorporates a regulated voltage output, VREF. The regulator provides a 2.8V output for use by the customer application. This regulator can source up to 100 mA of current to power any external digital circuits. VREF voltage is present whenever the W24 is powered up, regardless of it's mode of operation.Table 2-12: Controls and IndicatorsPin # Pin Name Description25 RESET_N W24 system readiness output indicator. When high, W24 is operating.27 VREF 2.75V regulated output.Supplies up to 100mA to the external circuits.26 WKUPO_N Host application wake-up signal indicator.16 WKUPI_N Device application wake-up sig-nal control.41 ANT_DET Antenna physical connection detect indicator.39 TXEN_N Transmission burst indication.49 GPRS GPRS/EGPRS coverage indica-tor.60 WIFI_LED_LCD_RS Wi-Fi Activity LED indicator.45 MSEL_UID Mode Select.
Controls and Indicators Interface28 Module Hardware Description March 31, 2008Important: The VREF regulator is powered from the W24's main power supply, and therefore any current sourced through this regulator originates from the W24 VCC supply. The overall VCC current consumed by W24 is directly affected by the VREF operation. The W24 current consumption rises with respect to the current drawn from VREF.Table 2-13 gives the VREF specifications.WakeupFor a detailed description regarding Wake up signal interface, please refer to “Low Power Mode” on page 16, paragraphs “Using the WKUPI_N signal” and “Using the WKUPO_N signal” .Antenna DetectionThe W24 incorporates an internal antenna detection circuit, which senses the physical connection and removal of a Wi-Fi antenna, as well as the cellular antenna, in case that a cellular module like G24 is stacked on the W24.In case of stacked configuration (W24 + G24), a removal of a single or both of the modules antennas, will cause the antenna detect indicator to be set Low.The antenna detection state is reported to the application through the ANT_DET output signal, and may also be queried by the AT+iRP19 command.The detection circuit senses DC resistance to ground on the G24 antenna connector.A DC resistance below 100kohm (+10%) is defined as a valid antenna connection, and the ANT_DET output signal is set high.GPRS/EGPRS DetectionThis signal is routed from the 70-pin host connector to G24 70-pin connector via W24. It is not internally connected to W24 circuits. If the W24 will be used as stand alone only, this signal pin should be left open.Table 2-13: VREF SpecificationsParameter Conditions Min Typ Max UnitVOUT IOUT = 150 mA 2.7 2.8 2.9 VIOUT Active mode - 100 mALoad regula-tionIOUT = 1.0 mA to 100 mA215mVLine regula-tionVin = VccIOUT = 1.0 mA110mV

Chapter 4: Mechanical Specifications March 31, 2008 Module Hardware Description 49W24 MountingThe W24 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 W24 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 W24 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 4-5 depict the W24 mounting area.Figure 4-5: W24 Mounting AreaW24 Stand Alone MountingThe holes are used for mechanical mounting of W24 to the application board but also for grounding support. Using conductive elements to install W24, significantly improves the overall grounding of the module and therefore improves the W24 performance and stability.It is required to use screws or other mechanical elements to fasten W24 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.Recommended screw type for static products: M2x4, PAN, SST
