WM_PRJ_Q24NG_PTS_001-003 November 2006 3.2.3 Power Consumption The Wireless CPU Q24 Series support different power consumption modes: Working modes Comments OFF mode The Wireless CPU is in OFF mode. ALARM mode The Wireless CPU is in OFF mode with RTC block running, when an ALARM occurs, the Wireless CPU wakes-up automatically. FAST idle mode The Wireless CPU is synchronized with an RF GSM/GPRS network. The internal 26 MHz of the Wireless CPU is constantly active. SLOW idle mode The Wireless CPU is synchronized with an RF GSM/GPRS tester. The internal 26 MHz of the Wireless CPU is not constantly active. FAST Standby mode The SIM and Radio interface are deactivated via AT command or Open AT API: -The embedded application is running -The serial port remains active (AT commands are available). The internal 26 MHz of the Wireless CPU is constantly active. SLOW Standby mode This mode is similar to the FAST Standby mode. All the features are disabled (no GSM, no GPRS, no SIM and no Serial port). The internal 26 MHz of the Wireless CPU is not constantly active. Communication mode A GSM/GPRS communication is established with a RF GSM/GPRS network. The power consumption depends on the configuration used. It is for this reason that the following power consumption values are given for each modes, RF bands and software used (AT or Open AT®). All the following information is given, by assuming a 50 Ω RF output. Three VBATT values are used to measure the consumption, VBATTMIN (3.2V), VBATTMAX (4.5V) and VBATTTYP (3.6V). The average current is given for three VBATT values and peak current given is the maximum current peak measured with three VBATT voltages. For more information on power consumption measurement, hardware configuration, SIM used, and software Dhrystone application, see the AT Command Interface Guide or OS 6.57 [5] and Wireless CPU Q24 Series Customer Design Guidelines [3]. When Wireless CPU is in Alarm mode, no voltage must be applied to any pin of the 60-pin connector, except on the BAT-RTC (pin 56) for RTC operation or ON/~OFF (pin 6) to power-ON the Wireless CPU. 3.2.3.1 Power Consumption without Open AT® Processing The following measurement results are relevant only when: • There is no Open AT® application, • The Open AT® application is disabled,](https://usermanual.wiki/Sierra-Wireless/Q24EX001/User-Guide-734426-Page-25.png)

WM_PRJ_Q24NG_PTS_001-003 November 2006 3.8.2 SIM Card Holder An optional SIM Card holder may be placed on top of Wireless CPU. This SIM Card holder does not use the SIM_PRES signal. Caution: Customers are advised to verify that the SIM Card environmental specification used is compliant with the Wireless CPU Q24NG environmental specifications [3] (see the Wireless CPU Q24NG Product Technical Specification WM_PRJ_Q24NG_PTS_001). Any application must be qualified by the customer with the SIM Card in storage, transportation and operation. Some ESD protections were placed to protect SIM form ESD stress; ESD protection position is described in Figure 6 and should be taken into account during a mechanical design.

WM_PRJ_Q24NG_PTS_001-003 November 2006 Caution: When speakers and microphones are exposed to the external environment, it is recommended to add ESD protection on the audio interface lines. 3.12.1 Microphone Inputs The MIC2 inputs already include the biasing for an electret microphone, thus allowing easy connection to a handset. The MIC1 inputs do not include an internal bias. MIC1/SPK1 may be used for a hands-free system or a handset, including biasing circuit for the microphone. The microphone connections may be either differential or single-ended, but using a differential connection in order to reject common mode noise and TDMA noise is strongly recommended. Caution: While using a single-ended connection, ensure to have a good ground plane, a good filtering as well as shielding, in order to avoid any disturbance on the audio path. 3.12.1.1 Common Microphone Input Characteristics Both microphone inputs are designed with the following audio transmit characteristics: Internal audio filter characteristics Frequency Gain 0-150 Hz < -22 dB 150-180 Hz < -11 dB 180-200 Hz < -3 dB 200-3700 Hz 0 dB >4000 Hz < -60 dB The gain in the MIC inputs are internally adjusted and may be tuned from -6.5 dB to 51.3 dB by using AT commands (refer to AT commands documentation [5]).](https://usermanual.wiki/Sierra-Wireless/Q24EX001/User-Guide-734426-Page-40.png)

To use these inputs with an electret microphone, bias must be generated outside the Wireless CPU Q24 Series in accordance with the characteristic of this electret microphone. These inputs are the standard inputs used either for an external headset or a hands-free kit. The impedance of microphone 1 must be around 2 kΩ. AC coupling is already embedded in the Wireless CPU.

Both speaker outputs may be represented as follows: Equivalent circuit 3.12.2.1 Common Speaker Output Characteristics The connection may be differential or single-ended, but using a differential connection to reject common mode noise and TDMA noise is strongly recommended. Moreover, in single-ended mode, the power is reduced by two, compare to the differential mode Caution: When using a single-ended connection, ensure to have a good ground plane, a good filtering as well as a good shielding in order to avoid any disturbance on the audio path. Speaker outputs SPK1 and SPK2 are push-pull amplifiers and may be loaded down to 150Ω and up to 1 nF The impedance of the speaker amplifier outputs in differential mode is: R ≤ 1 Ω +/-10 % . When speaker output is not used, the speaker interface is in three states and a 20K +/-30% impedance is kept between SPK1N and SPK1P as well as SPK2N and SPK2P. These outputs are differential and the output power may be adjusted by step of 2 dB. The output may be directly connected to a speaker. The gain in the speaker outputs are internally adjusted and may be tuned by using AT commands (refer to the AT commands documentation [5]).

Battery charging is performed through a switching transistor connecting the VBATT signal to the Charger (CHG_IN signal). The switching transistor is controlled by the operating system with two kinds of algorithms.

The BAT-TEMP ADC input must be used to sample the temperature analog signal provided by an NTC temperature sensor. The minimum and maximum temperature range may be set by an AT command (See the Li-Ion charging algorithm). 3.14.3 Ni-Cd / Ni-Mh Charging Algorithm During the charging process of a Ni-Cd and Ni-Mh battery, it is required to tune software parameters in the Wireless CPU operating system: AT+WBCM=<Mode>, <ChargeInd>, <BattLevelMax>, <BattLevelMin>, <TPulseInCharge>, <TPulseOutCharge>, <BattIntRes>, <BattChangeLevel > (See the AT command Interface Guide [5]).

Note: Instead of sending AT+CPOF, use the Wireless CPU external interrupt pin (see the External interrupt) 3.16 BOOT (optional) This input may be used to download software to the Flash memory of the Wireless CPU. For applications based on AT commands, this is a backup download procedure (refer to document [3] Customer Design Guidelines).

Caution: • This BOOT pin must be left open for normal use or Xmodem download. • The nominal firmware download procedure uses the Xmodem. In Internal BOOT mode, low level must be set through a 1KΩ resistor. • BOOT = logical state 0, for download mode and • BOOT = logical state 1, for normal mode.

As soon as the reset is completed, the AT interface answers "OK" to the application. In this case, the application must send AT↵. If the application manages hardware flow control, the AT command may be sent during the initialization phase. Another solution is to use the AT+WIND command to obtain an unsolicited status from the Wireless CPU. For further details, refer to the AT commands documentation [5].
