page 12/51 HiAllNC User Manual 2012/06/28 3.2 SIM CARD 3.2.1 Internal SIM card HiAllNC module embeds an IC SIM Card as an optional hardware feature (MFF2 format according to ETSI standard). To get information about internal IC SIM Card option, please contact SAGEMCOM. 3.2.2 External SIM card connection HiAllNC module provides also external SIM interface. Figure 2: Typical SIM schematic Figure 3: SIM card signals  Decoupling capacitors must be added on SIM_CLK, SIM_RST, SIM_VCC and SIM_DATA signals as close as possible to the SIM card connector to avoid EMC issues and in order to pass the SIM card approval tests.  SIM_VCC must be used only for the SIM card.  Use ESD protection components to protect SIM card and module I/Os against Electrostatic Discharges. ESD components must be placed as close as possible to the SIM. The following schematic shows how to
page 13/51 HiAllNC User Manual 2012/06/28 protect SIM access of the 6 pin connector. This must be performed every time when the SIM card holder is accessed by the end user.  If it is necessary to use long SIM bus lines of over 100mm, it is recommended to adopt serial resistors to avoid electrical overshoot on SIM bus signals. Use 56 Ω for the clock line and 10Ω for the reset and data lines.  To use external SIM detection function, a GPIO pad must be connected to SIM holder. Figure 4: SIM schematic with protection serial resistors & EXT_SIM_DET signal The schematic above includes a hardware SIM card presence detector. When SIM card is not inserted into SIM holder, Pin9 and Pin10 of SIM holder are disconnected. A GPIO detects a high level during boot. Then there is no initialization to SIM card. When SIM card is inserted, Pin9 is short to Pin10 by mechanic contact, and a GPIO detects a low level during boot.  A 22pF capacitor is recommended on EXT_SIM_DET.  SIM card must not be removed from its holder while it is still powered. Switch the module off properly with the AT command, then remove the SIM card from its holder. 3.2.3 SIM CARD priority The SIM card selection is performed thanks to KSIMSEL parameter. HiAllNC shall be configured to support to one of the following configuration: - KSIMSEL=0  external SIM only - KSIMSEL=1  internal SIM only - KSIMSEL=2  priority to external SIM if both SIM cards are presents Change of KSIMSEL value is taken into account only after reboot Use of EXT_SIM_DET is mandatory to support KSIMSEL=2 feature (see KSIMSEL description in reference [2])
page 14/51 HiAllNC User Manual 2012/06/28 3.3 AUDIOS The HiAllNC module provides both analogue and digital audio interfaces. 3.3.1 Analogue audio connection HiAllNC module features one input path and one output path for analogue audio. Both the input path and the output path are differential. The design examples in the following chapter will take into account the EMC, ESD protections, and reducing the possible TDMA noise in sensitive area by performing the given routing rules.  Note that acoustic engineering competences are mandatory to get accurate audio performance on customer’s product. 3.3.1.1 Connecting microphone and speaker HiAllNC module can manage an external microphone (MIC_P/MIC_N) in differential mode and an external speaker (HSET_OUT_P / HSET_OUT_N) in differential mode. Thus, one speaker and one microphone can be connected to the module. The 1.4V voltage to bias the microphone is implemented in the module.  The speaker connected to the module should be 32 ohms. ESD protection Figure 5: Analogue audio connection If the design is ESD or EMC sensitive, we strongly recommend reading the notes below. A poor audio quality could either come from the PCB routing and placement or from the chosen components (or even both). 3.3.1.1.1 Notes for microphone  Pay attention to the microphone device, it must not be sensitive to RF disturbances.  As described in the layout chapter, differential pairs must be routed in parallel and same length (MIC_P and MIC_N signals)  If you need to have deported microphone out of the board with long wires, you should pay attention to the EMC and ESD effect. In those cases, add the following protections to improve your design.  To ensure proper operation of such sensitive signals, they have to be isolated from the others by analogue ground on customer’s board layout. (Refer to Layout design chapter) HiAllNC Speaker MIC
page 15/51 HiAllNC User Manual 2012/06/28 Figure 6: Filter and ESD protection of microphone 3.3.1.1.2 Notes for speaker As explained for the microphone, if the speaker is deported out of the board or is sensitive to ESD, use the schematic here to improve the audio. Figure 7: Filter and ESD protection of 32 ohms speaker  HSET_OUT_P, HSET_OUT_N tracks must be larger than other tracks: 0.1mm.  As described in the layout chapter, differential pairs must be routed in parallel and same length (HSET_OUT_P and HSET_OUT_N signals)  The impedance of audio chain (filter + speaker) must be lower than 32Ω.  To use an external audio amplifier connected to a loud-speaker, use serial capacitors of 10nF on HiAllNC audio outputs to connect the audio amplifier.

page 17/51 HiAllNC User Manual 2012/06/28 Distortion 5% max at 1K Hz, nominal input power 3.3.1.3 DTMF OVER GSM network Former systems used to transmits data through DTMF modulation on RTC telephone lines.  Audio DTMF tones are not guaranteed over GSM network This is due to the nature of the GSM Voice CODEC - it is specifically designed for the human voice and does not faithfully transmit DTMF. When you press the buttons on your GSM handset during a call, this goes in the Signalling channel - it does not generate in-band DTMF; the actual DTMF tones are generated in the network. Therefore if your design needs the DTMF functionality, you should know their transmission over the network is not at all guaranteed (because of voice codec). This could work or fail depending very strongly on the GSM network provider. SAGEMCOM does not guarantee any success on using this function. However tests on HiAllNC shown this feature can work on some GSM Networks. Successful transmissions and receptions have been done with 300ms of characters duration and 200mVpp as input level on microphone input.  If this function is needed, first try with your network and those parameters then (if success) try to tune them to fit your specification. 3.3.2 Digital PCM Audio The HiAllNC module features a PCM interface. The PCM interface is a high speed full duplex interface that can be used to send and receive digital audio data to external audio ICs.The HiAllNC PCM interface is highly configurable: - PCM master or slave mode - 8bits or 16 bits data word length - MSB or LSB first - Rising or falling sampling clock edge - Configurable PCM bit clock rate up to 1MHz Signals Module connector pin number Description PCM_CLK 21 Clock PCM_IN 66 Digital audio input PCM_OUT 65 Digital audio output PCM_SYNC 22 Audio signal frame synchronization
page 18/51 HiAllNC User Manual 2012/06/28 Figure 9: PCM interface timing 3.4 POWER SUPPLY HiAllNC module can be supplied by a battery or by any DC/DC converter compliant with the input voltage range from 3.3V to 4.5V and 2A current capability.  >VBAT traces are required to be as short and as wide as possible.  VBAT ceramic decoupling capacitors of at least 100µF/10V are required to ensure good RF performance. It is strongly recommended to place capacitors close to the module’s connection pad and connected via low resistance tracks to VBAT and GND.  PCB tracks must be well dimensioned to support 2 A maximum current (Burst current 1.8A plus the extra current for the other used I/Os). The voltage ripple caused by serial resistance of power supply path (Battery internal resistance, tracks and contact resistance) could result in the voltage drops.  To prevent any issue in the power up procedure, the typical rise time for VBAT should be around 1ms.  HiAllNC module does not manage the battery charging. 3.4.1 Burst conditions Communication mode (worst case: 2 continuous GSM time-slot pulses): Figure 10: GSM/GPRS Burst Current rush  A 47µF with Low ESR capacitor is highly recommended for VBAT and close to the module pins 43/44.
page 19/51 HiAllNC User Manual 2012/06/28 3.4.2 Ripples and drops Figure 11: GSM/GPRS Burst Current rush and VBAT drops and ripples  The minimum voltage during the drop of VBAT must be 3.3V at 33dBm for the full range of the required functioning temperature. To reach this aim, adapt the VBAT tracks width to minimize the loss: the shorter and thicker is the track; the lower is the serial impedance. To check the serial resistor, any CAD software can be used or by experiment by measuring it on the PCB by injecting 1A into the VBAT tracks on connector side and shorting the other side to GND, this could be done using a laboratory power supply set to few volts with a limitation in current to 1A. Then the measure of the drop voltage leads to the serial resistor.  Noise on VBAT due to drops could result in poor audio quality.  Serial resistor should be less than 250mΩ including the impedance of connectors.  Ripple has to be minimised to have a clean RF signal. This can be improved by filtering the output of the power supply when AC/DC or DC/DC components are used. Refer to the power converter chip supplier application note for more information and advice. 3.4.3 EXAMPLE OF POWER SUPPLIES 3.4.3.1 DC/DC Power supply from a USB or PCMCIA port. It the following application note from Linear Technology LTC3440, this schematic is an example of a DC/DC power supply able to power 3.6V under 2A. This can be used with an AC/DC 5V unit or an USB or PCMCIA bus as input power source. C6 to C9 can be followed by a serial MOS transistor to avoid a slow rise signal at VOUT. 3.3V Min Ripple VBAT drop Current burst at 1.8A 33dBm GSM TX Lev 5

page 21/51 HiAllNC User Manual 2012/06/28 Figure 14: Example with Linear LT1913 3.4.4 Avoid side effects of a retro supply (current re-injection) Interactions or connections between HiAllNC module and the external systems can lead to retro power supply side effects, or current re-injection through pads while the module is not yet fully powered up (means VBAT lower than its minimum 3.3V). If some precaution and simple rules are not followed, those effects can in worst case result in a deadlock module, not able to start up or to communicate. Deadlock could happen if the retro supply occurs before the module start. The flow back current could in the worst case prevent the module to start. The same behaviour can happen in a normal use conditions when the lines connecting to the module to the external system uses a non compliant voltage higher than the module IO power domain. This results in a current flow back inside the module and can lead to a deadlock system on the next start if this retro supply has continued while the system was powered off or under powered (under 3.3V). An over voltage on any line can also damage HiAllNC module. Those consequences are rare but exist. Therefore, the rules and advises given on every chapter of this application note must be followed. To avoid any power up issue, here are the rules:  Avoid any over voltage on the bus lines connected to the module. • Use the same power domain voltage for HiAllNC lines. • Use voltage level translators when the power domain requires it  When the module is powered-off, do not apply any voltage on lines connected to the module. • Power-off the bus lines connected to the HiAllNC module, to avoid any flow back current (re-injection). • Power-off the I/Os connected to the HiAllNC, to avoid any current loss.  Recommendations for power domains • To avoid any current re-injection on VANA (2.85V), o Use a 10µF serial capacitor to block the DC voltage when an external bias voltage over VANA is used for the microphone.
page 22/51 HiAllNC User Manual 2012/06/28 o Use external resistor divider to limit the ADC input voltage when measured a voltage higher than VANA. o Do not connect the UART lines (TXD, RXD, RTS, CTS) to any other voltage. • To avoid any current re-injection on VGPIO (2.80V), o Do not connect a power supply to the VGPIO pad. This pad is an LDO output only. o The host must supply all the GPIOs connected to HiAllNC with correct voltage in compliance with the power domain, and must shut off the GPIOs when the module is off. o The SPI bus must not connect to the external system. o The JTAG bus must not connect to the external system. • To avoid any current re-injection on VPERM (3.0V) o The POK_IN signal is internally pulled up and can be connected to an open drain transistor. • To avoid any current re-injection on VBACKUP (3.0V) o The VBACKUP signal must be only connected to a DC coin 3V battery or a capacitor. • To avoid any current re-injection on SIM_VCC (1.8V or 2.9V) o Use only SIM_VCC pads to supply the SIM card or SIM IC. • To avoid any current re-injection on VBAT (3.3V to 4.5V) o Decrease the rising time (recommended value <1ms ) as much as possible for VBAT. o Use serial capacitor (10µF) to isolate the audio speaker lines to the external system if necessary. 3.5 UARTS HiAllNC module has a main UART port that can be used in low-speed, full-speed, and high-speed modes. The UART communicates with serial data ports conforming to the RS-232 interface protocol. With a properly written and user-defined download program, the UART port can be used for testing and debugging.  Provision of external access to the V24 interface for easy upgrade of software is recommended.  Baud rate up to 1Mbps  Unused signals can be left unconnected. Signal name (DCE side) Signal name (DTE side) Signal use (DTE side) UART1_DTR DTE_DSR Signal UART interface is ON UART1_DCD DTE_DCD Signal data connection in progress UART1_RXD DTE_TXD Transmit data UART1_RTS DTE_CTS HiAllNC is ready to receive AT commands UART1_TXD DTE_RXD Receive data UART1_CTS DTE_RTS Wakes up the module when Ksleep=1 is used UART1_RI DTE_RI Signal incoming calls (voice and data), SMS, etc. UART1_DSR DTE_DTR Prevents the HiAllNC from entering sleep mode Switches between data mode and command mode Wakes the module up.
page 23/51 HiAllNC User Manual 2012/06/28 HiAllNC module has another reduced UART port. Its application is similar as the reduced case of main UART. Thus, this document describes only for main UART in the following chapter. 3.5.1 Complete V24 connection of HiAllNC to host HiAllNC provides a V24 interface with the following signals: UART1_RTS/ UART1_CTS, UART1_RXD/ UART1_TXD, UART1_DSR, UART1_DTR, UART1_DCD, UART1_RI.  Use of this complete V24 connection is required whenever your application exchanges data. Figure 15: Complete V24 connection of HiAllNC to host processor This configuration allows the use of the flow control UART1_RTS & UART1_CTS to avoid overflow error during the data transfer. In addition, UART1_RTS is used to inform DTE whether the HiAllNC is ready to receive an AT command after power up sequence or wake up from the sleep mode. Figure 16: UART1_CTS versus POK_IN signal during the power on sequence. This signal configuration also enables all signals: • UART1_RI signal is used when programmed to indicate an incoming voice or data call or SMS incoming message etc… • UART1_DCD signal is used to indicate GPRS connections. • UART1_DTR signal is used to indicate that the module’s UART interface is ON. • UART1_DSR signal is used to prevent the HiAllNC from entering sleep mode, switching between Data and AT commands, hanging up a call or waking up the module etc.
page 24/51 HiAllNC User Manual 2012/06/28  Avoid supplying power to the main UART before the HiAllNC is ON, as this may result in power up sequence error. 3.5.2 Complete V24 interface with PC It supports speeds up to 1Mbps (115.2 Kbps with auto bauding). To use the V24 interface, some level shifter components are necessary, as HiAllNC signals need to be converted to +/- 5V signals compatible with a PC. Figure 17: Connection to a data cable  Avoid supplying the UART before HiAllNC module is ON, as this could result in power up sequence error. To create your own data cable (for software download purpose…etc…) refer to the following schematic as an example with a MAX3238E: • VCC_3V1 is an LDO output (VBAT to VCC_3V1) enabled by VGPIO from the module. Yet it can be any voltage between 3V and 5V (see MAX3238E or MAX3237E specification). • 180Ω are serial resistors aimed to limit the EMC and ESD propagation. • Additional voltage level translator must be added to the design when GPIO of HiAllNC module was set to 1.8V mode.
page 25/51 HiAllNC User Manual 2012/06/28 Figure 18: Example of a connection to a data cable with a MAX3238E 3.5.3 Partial V24 (RX-TX-RTS-CTS) connection of HiAllNC to host When using only UART1_RXD/ UART1_TXD/ UART1_RTS/ UART1_CTS instead of the complete V24 link, the following schematic could be used. Figure 19: Partial V24 connection (4 wires) of HiAllNC to host processor  As UART1_DTR is active (low electrical level) once HiAllNC is switched on, UART1_DSR is also active (low electrical level), therefore the AT command AT+KSLEEP can switch between the two sleep modes.  UART1_DCD and UART1_RI can remain disconnected and floating when not in use. Otherwise use 100KΩ to pull up to power. This configuration allows use of flow control UART1_RTS & UART1_CTS to avoid overflow error during data transfer. Moreover UART1_RTS is used to indicate when the HiAllNC module is ready to receive an AT
page 26/51 HiAllNC User Manual 2012/06/28 command after power up sequence or wake up from sleep mode.  UART1_RI signal is a stand alone signal that can be used with any one of the following configuration. Consult the AT command specification for more information about this signal and its use.  This configuration allows to use the flow control UART1_RTS & UART1_CTS to avoid any overflow error during the data transfer, UART1_CTS is moreover used to signal when the HiAllNC is ready to receive an AT command after a power up sequence or a wake up from sleep mode.  However this configuration does not allow signals such as: • UART1_RI signal used when programmed to indicate an incoming voice or data call or SMS incoming etc… • UART1_DCD signal used to indicate DATA connections. • UART1_DTR signal used to indicate module UART interface is ON. • UART1_DSR signal is used to prevent HiAllNC from entering sleep mode or to switch between DATA and AT commands or to hang up a call or to wake up the module etc…. 3.5.4 Partial V24 (RX-TX) – connection HiAllNC - host When using only UART1_RXD/ UART1_TXD instead of the complete V24 link, the following schematic could be used. Figure 20: Partial V24 connection (2 wires) of HiAllNC to host processor  As UART1_DTR is active (low electrical level) once HiAllNC is switched on, UART1_DSR is also active (low electrical level), therefore the AT command “AT+KSLEEP” can switch between the two available sleep modes.  As UART1_RTS is active (low electrical level) once HIALLNC is switched on, UART1_CTS is also active (low electrical level), therefore the AT command “AT+ KSLEEP” can switch between the two available sleep modes. The HiAllNC firmware allows activation of UART1_RTS during sleep state even when looped to the UART1_CTS signal.  Note that this configuration does not allow the below signals: • UART1_RI signal used when programmed to indicate an incoming voice or data call or incoming SMS etc…. • UART1_DCD signal used to indicate GPRS connections. • UART1_DTR signal used to indicate the module UART interface is ON. • UART1_DSR signal used to prevent the HiAllNC module from entering sleep mode.
page 27/51 HiAllNC User Manual 2012/06/28 3.6 SPI HiAllNC module manages a host SPI interface. This SPI interface is only dedicated for software traces.  SAGEMCOM strongly recommends leaving this interface externally accessible for SW traces (e.g. access by test point pads) In case of needs SAGEMCOM may request to connect a dedicated trace cable to the customer’s electronic board. If tests points have been foreseen, simply solder 5 wires to a small HE10 male connector using the following schematic. This connector will be linked to the dedicated cable and used to log the software traces with a PC software provided by SAGEMCOM. Figure 21: SPI HE10 pin – TOP VIEW 3.7 GPIOS Six GPIOs are available on HiAllNC. All GPIOs have optional internal pull-up resistors. Customer applications can directly access them through appropriate AT commands such as: • Output: pin is set to High or Low state • Input: pin is read on request and customer application is responded to. Different scenarios are possible to cover a maximum range of customer applications: • Synchronous answer to AT command • Asynchronous answer to AT command Customer’s application prior to the read request has configured the GPIO to react to falling/rising edges. The customer application is notified asynchronously by AT command answer when the configured trigger occurs. By using other special AT commands, GPIOs can be used to, for example: • to make an I/O toggling while the module is attached to the network • to make an I/O toggling when a programmed temperature is reached • as input to detect the presence of an antenna (with some external additional electronic circuit) • as input to detect the SIM card presence …etc GND (White) SPI_OUT (Red) SPI_CLK (Yellow) SPI_IRQ (Green) SPI_SEL (Brown) SPI_IN (Black) VCC_3.7V (Blue) NC Male connector located on the Customers' hardware (HE10 male 8 pins)
page 28/51 HiAllNC User Manual 2012/06/28 3.8 ADCS Two ADC input pads are available on HiAllNC module, which can be used to read the value of the voltage applied. Following characteristics must be met to allow proper performances: • The input signal voltage must be within 0V to 3V • The input impedance of the pad is 150KΩ • The input capacitance typically is 10pF. • 10 bits resolution • Maximum sampling frequency is 200KHz. 3.9 BACKUP BATTERY 3.9.1 Backup battery function features A backup battery can be connected to the module in order to supply internal RTC (Real Time Clock) when the main power supply is disconnected. With external backup battery: • If VBAT < 3V, internal RTC is supplied by VBACKUP. • If VBAT ≥3V, internal RTC is supplied by VBAT.  Without backup battery • If VBAT ≥ 1.5V, internal RTC is supplied by VBAT. • If VBAT < 1.5V, internal RTC is not supplied.  VBACKUP input of the module has to be connected to a 10µF capacitor (between VBACKUP and GND). 3.9.2 Current consumption on the backup battery When the power supply is removed, the internal RTC will be supplied by backup battery.  To calculate the backup battery capacity, consider that current consumption for RTC on the backup battery is up to 1000µA in worst case conditions. Signals Min current Max current VBACKUP 1000µA 3.9.3 Internal HiAllNC charging function HiAllNC has a charging function that does not require any additional external power supply (power supply for the charging is provided by the HiAllNC).  Charge of the back-up battery occurs only when main power supply VBAT is provided. The recommended schematic is given hereafter:
page 29/51 HiAllNC User Manual 2012/06/28 Figure 22: internal charging of backup battery or 10uF capacitor The value of resistor R depends on the charging current value of the backup battery manufacturer. 3.9.4 Capacitor backup battery technology  SAGEMCOM strongly recommends using Supercap technology. These kinds of backup battery have not the drawbacks of the Lithium Ion rechargeable battery. As there are only capacitors: • The maximum discharge current is generally bigger, • There is no problem of over-discharge: the capacitor is able to recover its full charge even if its voltage has previously fallen to 0V. • There is no need to regulate the charging current. Moreover, this kind of battery is available in the same kind of package than the Lithium Ion cell and fully compatible on a mechanical point of view. The only disadvantage is that the capacity of this kind of battery is significantly smaller than Manganese Silicon Lithium Ion battery. But for this kind of use (supply internal RTC when the main battery is removed), the capacity is generally enough. VBACKUP HiAllNC 10µF capacitor VBACKUP HiAllNC R Backup battery

POWER MANAGEMENT VBAT Input voltage shall be in the range 3.3V to 4.5V. 6.1 POWER MODES Depending on the status of the HiAllNC, different power consumption modes can be identified.  Communication mode (with or without GPS running) All systems on HiAllNC are active. In this mode, the module is registered to the network and a voice/data call is actively transmitting data.  Idle mode (with or without GPS running) In this mode, the module is registered to the network but it is idle/ paging only. No voice/ data call connection is established. AT commands can be send and GPS can run.  Sleep mode (without GPS running) In this mode, the module is registered to the network but it is idle/ paging only. No voice/data call connection is established. AT commands can not be send.  Flight mode (with or without GPS running) The processor is still active but the radio section is powered down. This mode can be controlled by sending an AT command to the module. 6.2 MODULE POWER-UP 6.2.1 Power-up with POK_IN signal To start the module, first power up VBAT, which must be in the range 3.3V ~ 4.5V, and must be able to supply 1.8A during TX bursts.  POK_IN is a low level active signal internally pulled up to a dedicated power domain of 3V. As POK_IN is internally pulled up, a simple open collector or open drain transistor must be used for ignition. Warning: The POK_IN will become low after module is ready. It can not be directly driven by a GPIO signal.  To start the module, a low level pulse must be applied on POK_IN for 2000ms.  RESET must not be Low during that period of time After a few seconds, the UART1_RTS enters active state and the module is ready to receive AT commands.  VGPIO is a supply output from the module that can be used to check if the module is active. • When VGPIO = 0V the module is OFF. • When VGPIO = 2.8V the module is ON. (It can be in Idle, communication or sleep modes)
page 36/51 HiAllNC User Manual 2012/06/28 Figure 24: Power ON sequence 6.2.2 IO DC Presence before Power on When VBAT is available but the module has not yet powered up, the following I/O's raise their output. POK_IN raise to 3V VBACKUP raise to 3V HSET_N raise to 1.4V HSET_P raise to 1.4V 6.2.3 MODULE RESET To reset the module, a low level pulse must be sent on RESET pin during 10 ms. This action will immediately restart the HiAllNC module. It is therefore useless to perform a new ignition sequence (POK_IN) after.  SAGEMCOM recommends using this feature in case of emergency, freeze of module or abnormal longer time to respond to AT Commands, this signal is the only way to get the control back over the HiAllNC module.  RESET is a low level active signal internally pulled up to a dedicated power domain. As RESET is internally pulled up, a simple open collector or open drain transistor can be used to control it.

page 37/51 HiAllNC User Manual 2012/06/28 The RESET signal will reset the registers of the CPU and reset the RAM memory as well.  As RESET is referenced to VGPIO domain (internally to the module) it is impossible to make a reset before the module starts or try to use the RESET as a way to start the module. An other solution more costly would be to use MOS transistor to switch off the power supply and restart the power up procedure using the POK_IN input line 6.3 POWER ON AND SLEEP DIAGRAMS Those 2 diagrams show the behaviours of the module and the DTE during the power on and then in the sleep modes.

page 40/51 HiAllNC User Manual 2012/06/28 6.4 MODULE POWER OFF AT command “AT*PSCPOF” allows for correct power-off of the HiAllNC module. In case of necessary the module can be powered off by controlling the power supply. This can be used for example when the system freezes and no reset line is connected to the HiAllNC. In this case the only way to get the control back over the module is to switch off the power line. If the system is on a battery, it is wise to have a control of the power supply by a GPIO with for example the following schematic. Figure 26: Power supply command by a GPIO  This kind of schematic could also be used to save few micro amperes in case of need. As the module has a drain current of up to 56µA, this kind of function could lower it to the current through R4. These, are the behaviours of the VGPIO and the CTS signal during the power off sequence. Figure 27: Power OFF sequence for POK_IN, VGPIO and CTS POK_IN is low VGPIO Module is ON Module is OFF Typ 2 seconds AT*PSCPOF CTS POK_IN is high
page 41/51 HiAllNC User Manual 2012/06/28 6.5 MODULE SLEEP MODE The AT command “AT+KSLEEP” allows to configure the sleep mode. When AT+KSLEEP=1 is configured: • The HiAllNC module decides by itself when it enters in sleep mode (no more task running). • “0x00” character on serial link wakes up the HiAllNC module. When AT+KSLEEP=0 is configured: • When UART1_DTR is deactivated (high electrical level), the HiAllNC module enters in sleep mode after a while. • On UART1_DTR activation (low electrical level), the HiAllNC module wakes up. When AT+KSLEEP=2 is configured: • The HiAllNC module does not enter in sleep mode. In sleep mode the module reduces its power consumption and remains waiting for the wake up signals either from the network (i.e. Read paging block depending on the DRX value of the network) or the operating system (i.e. timers wake up timers activated) or the host controller (i.e. character on serial link or UART1_DTR signal).
page 42/51 HiAllNC User Manual 2012/06/28 7. ESD & EMC RECOMMENDATIONS 7.1 HiAllNC MODULE HiAllNC module alone can hold up to 2KV on each of the 116 pads including the RF pad. 7.2 Module handling HiAllNC modules are designed and packaged in tape-and-real for factories SMT process. HiAllNC modules contain electronic circuits sensitive to human hand's electrostatic electricity. Handling without ESD protection could result in permanent damages or even destruction of the module. 7.3 Customer’s product with HiAllNC If customer’s design must stand more than 2kV on electrostatic discharge, following recommendation must be followed. 7.4 Analysis ESD current can penetrate inside the device via the typical following components: • SIM connector • Microphone • Speaker • Battery / data connector • All pieces with conductive paint.  In order to avoid ESD issues, efforts shall be done to decrease the level of ESD current on electronic components located inside the device 7.5 Recommendations to avoid ESD issues  Insure good ground connections of the HiAllNC module to the customer’s board.  Flex (if any) shall be shielded and FPC connectors shall be correctly grounded at each extremity.  Put capacitor on battery 100nF or varistor or ESD diode in parallel on battery and charger wires (if any) and on all power wires connected to the module.  Uncouple microphone and speaker by putting capacitor or varistor in parallel of each wire of these devices.
page 43/51 HiAllNC User Manual 2012/06/28 8. RADIO INTEGRATION  Radio engineering skills are mandatory to get accurate radio performance on customer’s product 8.1 GSM antenna connection RF lines shall match 50 ohms impedance In order to achieve optimum sensitivity and output power in radiated mode, it is strongly recommended to implement a matching circuit, as shown on schematic below Figure 28: GSM antenna connection schematic More information about GSM radio design can be found in [3]. 8.2 GNSS antenna connection 8.2.1 Reference schematics HiAllNC module supports both passive and active antenna.  HiAllNC embeds a high performance SAW filter. No external filtering is required.  Typical schematic for passive antenna is similar to GSM antenna schematic above.  If active antenna use, HiAllNC module can be configure to output a GPS_LNA_EN signal, allowing disabling the external LDO when GNSS receiver is in stand-by or shut-down mode. Enabling GPS_LNA_EN is performed through AT+GNSSRUN command  If active antenna connection, a power supply shall be connected to the GNSS feed point, according to schematic example below:
page 44/51 HiAllNC User Manual 2012/06/28 Figure 29: GNSS active antenna connection schematic 8.2.2 Antenna detection For passive antenna, the command AT+KGNSSAD can be used to perform antenna detection. For active antenna, a GPIO can be used to detect the antenna power consumption. The customer needs to fit the current sense circuitry on its own board and match the detection level to the VGPIO level. 8.3 RADIO LAYOUT DESIGN Radio layout guidelines are defined in document [3]
page 45/51 HiAllNC User Manual 2012/06/28 9. AUDIO INTEGRATION FTA audio mandatory tests only deal with handset mode so a particular care must be brought to the design of audio (mechanical integration, gasket, electronic) in this mode. The audio related standard are 3GPP TS 26.131 & 3GPP TS 26.132.  Note that acoustic competences are mandatory to get accurate audio performance on customer’s product. 9.1 MECHANICAL INTEGRATION AND ACOUSTICS Particular care to Handset Mode: To achieve a more ideal audio output design (speaker part):  The speaker must be completely sealed on front side.  The front aperture must be compliant with the speaker supplier’s specifications  The back volume must be completely sealed.  The sealed back volume must be compliant with the speaker supplier’s specifications  Pay attention to the design of the speaker gasket (elastomer).  Make sure to leave sufficient space for the artificial ear gasket. To achieve a more ideal audio input design (microphone part):  Pay attention to the design of the microphone (elastomer).  All receivers must be completely sealed on front side.  Microphone sensitivity depends on the shape of the device but should be in the range of –40 ±3 dBV/Pa.  Recommend to use the pre-amplified microphone. If needed, use a pre-amplification stage. As audio input and output are strongly linked:  Place the microphone and the speaker as far away as possible from one another. 9.2 ELECTRONICS AND LAYOUT Avoid Distortion & Burst noise  Audio signals must be symmetric (same components on each path).  Differential signals must be routed in parallel.  Audio layer must be surrounded by 2 ground layers.  The link from one component to the ground must be as short as possible.
page 46/51 HiAllNC User Manual 2012/06/28  Separate the PCBs for the microphone and the speaker if possible.  Reduce the number of electronic components as much as possible (to avoid loss of quality and greater dispersion).  Audio tracks must be larger than 0.5 mm.
page 47/51 HiAllNC User Manual 2012/06/28 10. LAYOUT RECOMMENDATIONS ON CUSTOMER BOARD 10.1 GENERAL RECOMMENDATIONS ON LAYOUT There are many different types of signals in the module which may be interfered each other. Particularly, Audio signals are very sensitive to external signals such as VBAT... Therefore it is very important to follow some rules to avoid signal disruption or abnormal behaviour.  Magnetic fields generated by VBAT tracks may cause speaker interference and burst noise. In this case, modify layout of the VBAT tracks to reduce the phenomenon. 10.1.1 Ground  Ensure the ground plane is as complete as possible  Grounding of components should be connected to the ground layer through a number of irregularly distributed vias.  Top and bottom layer should set aside as much space for the ground plane as possible. Flood remaining empty surfaces of the layout of those two layers with a ground plane connected to the main ground through as many vias as possible.  Proper grounding is crucial to end-product performance. At least one layer must be a dedicated ground plane. This ground plane is the common point referenced by all end-product circuits.  In addition to the dedicated ground plane layer, unused space on all PCB layers should be filled with grounding to provide the most robust grounding possible from layer to layer.  Bypass capacitors should be connected directly to their surface layer ground fill. Multiple vias should connect each capacitor directly to the main ground plane, with one via in the capacitor’s pad plus several vias within the surface layer ground fill area.  Digital ground should connect directly to the main ground plane. In addition, each layer between layer 1 and the main ground should include ground fills directly below the center grid area’s digital pins, with each stack of vias connecting to each ground fill area. The large mass of copper tied together using this technique provides optimal electrical grounding and thermal conductivity.  The analog/RF ground pins are connected to each other, but isolated from the digital ground (until main ground). Like the digital pins, the analog/RF pins should connect directly to the main ground plane. In addition, each layer between layer 1 and the main ground should include ground fills directly below the outer layer’s analog/RF pins, with each stack of vias connecting to each ground fill area. The large mass of copper tied together using this technique provides optimal electrical grounding and thermal conductivity. 10.1.2 Power supplies  A layer for power supply signals (VBAT, VGPIO,SIM_VCC_VCC) is recommended.  Looping of power signal layouts must be avoided in device design.  Ensure suitable power supply (VBAT, VGPIO,SIM_VCC) track width and thickness.
page 48/51 HiAllNC User Manual 2012/06/28 10.1.3 Clocks  Clock signals must be shielded between two grounds layer and bordered with ground vias. 10.1.4 Data bus and other signals  Data bus must be routed on the same layer with equivalent track length and avoiding long parallel routing.  Lines crossings shall be perpendicular  Suitable signals track width, thickness for other signals.  Data bus must be protected by upper and lower ground plans 10.1.5 Radio  Provide a 50 Ohm micro strip line for antenna connection  For RF matching components do not locate matching inductors too close to shield walls (this may cause electromagnetic coupling and inductor de-Q). 10.1.6 Audio  Differential signals have to be routed together, parallel (for example HSET_OUT_P/HSET_OUT_N, MIC_P/MIC_N).  Audio signals have to be isolated, by pair, from all the other signals (ground all around each pair).  Cancel any loops between VBAT and GND next to the speaker to avoid the TDMA burst noise in the speaker during a communication.  The single-end audio signal should be adopted the same rules as differential signals.
