Confidential HI-TECH COMPANY 5.3 GSM/GPRS Data Module P.n.: 3-2000733 RF High POWER Core of RF part is the SMARTiSD2 transceiver which performs modulation and up-conversion of I/Q signal as well as down-conversion and demodulation of the RF received signals. The interface between E-GOLDlite and SMARTiSD2 is balanced I/Q analog signal, time shared by transmitter and receiver. Programming of SMARTiSD2 transceiver is done through dedicated 3-wires interface of E-GOLDlite. Timing are provided by the built-in GSM Timer Unit of E-GOLDlite; the antenna switch and PA are commanded via trigger signal TOUT0, TOUT[2..3]. SMARTiSD2 provides two different RF TX outputs respectively for 850/900 and 1800/1900 bands. TriQuint TQM7M4006 PA amplifies these signals maintaining two separate paths. The PA is directly connected to the VBAT supply. The power ramp control is provided by E-GOLDlite to the PA module, which has a built-in power controller. Quad Band Epcos antenna switch integrates SAW filters and matching for all the RX paths. It is directly connected to the RX inputs of SMARTiSD2. The RF I/O signal is by default provided to 50ohm SMA connector. Printed antenna is selectable as RF I/O interface by soldering some matching components.

Phone design includes the following interfaces: • SIM card holder supporting 1.8 and 3V card type. • System connector on phone with serial data I/O with handshake signals. Outside phone design there are the following interfaces: • 2 UART: ASC0 with hardware handshake signals and ASC1 without flow control. Both of them are accessible on Molex board-to-board connector and supports high speed dataflow. • Debug connectors (JTAG) for C166 and for TEAKlite debug tools.

Confidential HI-TECH COMPANY GSM/GPRS Data Module P.n.: 3-2000733 • The maximum storable file size is 1 MB. • The maximum FFS data write rate is 20 Kbytes/s. Page mode is supported for enhanced system performance. 5.6 Clock The 26MHz master clock is generated by SMARTiSD2 with a fully integrate digital controlled crystal oscillator (DCXO), whose signal is used as a reference frequency for the radio synthesizer and also provided to the baseband IC, after a buffer amplifier. The only external component needed for oscillator is a quartz crystal. The oscillator and buffer are supplied by VRF2: powering it up activates the 26MHz clock. The baseband provide Automatic Frequency Correction (AFC) to SMARTiSD2 with control words sent on the 3wires interface to guarantee the GSM frequency stability requirements. E-GOLDlite has built-in Clock Generation Unit (CGU) that generates and distributes the suitable clock signals to all the baseband sections. The Real Time Clock (RTC) is implemented with a 32 KHz quartz crystal for E-GOLDlite internal oscillator.

In standard mode, the microphone signal comes from the external stereo head-set device and is connected to MICP2/MICN2 inputs of E-GOLDlite. Voice output from E-GOLDlite EPP1 is connected to the Stereo Audio Amplifier (in mono), and then to the external audio device. In viva voice mode of operation, the output signal of EPP1/EPN1 is amplified by the built-in Audio amplifier of EPOWERlite, and then applied to the Loudspeaker output. Loudspeaker (mechanical assembled with earpiece) is connected by pass-through wires on the top of the display module. 5.7.3 Ringer Mode The ringer tones are generated by E-GOLDlite built-in generator and then they are amplified by E-POWERlite amplifier before being applied to loudspeaker. Otherwise, the generated ringer signal might be applied to the Stereo audio amplifier that serves the head-set external device.

Confidential HI-TECH COMPANY GSM/GPRS Data Module P.n.: 3-2000733 5.10 Power Saving Power saving is a special function that allows the reducing of power consumption during the idle time. If the clock increases, required power increases too. Therefore a solution for minimizing the power is the reducing of the master clock frequency when there aren’t activities. In this period the system doesn’t work with a clock of 26 MHz (“fast clock”) but with a clock of 32 KHz (RTC clock or “slow clock”). This switching between 26 MHz and 32 KHz clock is performed by SCCU (Standby Clock Control Unit). Main priorities of power saving are the following: 1. Reduce base (min) current consumption; 2. Minimize full-speed running periods, minimize power saving on/off switching; 3. Reduce max current consumption. These points are reported in the following figure: Image 12: Power saving priorities 5.10.1 E-POWERlite If the voltage decreases, the power decreases too. VCXO_en control voltage is applied to E-POWERlite to selectively shutdown supply voltage lines LRF0, LRF1 and LRF2 for radio frequency part. VCXO_en control voltage is used in PWM Ù PFM StepDown converter, since PFM mode requires less switching (less power) than PWM on light loads.

Since Enable is active low (and inactive high), it is forced low before enter power saving, else SMARTi will be pseudo supplied via Enable input junctions. This may be very harmful for relevant BaseBand output port HW and consumes power. Enable is restored high when power saving exits. Moreover SMARTi has also to be reinitialized, just like the first power up (stealth telegrams). Image 14: SMARTi comportament during Power Saving 5.10.3 Serial ports It is impossible to receive and send on Asynchronous Serial Communication (ASC) ports at standard speeds in power saving. DCE serial port relies on hardware flow control logic. DTE shall cache serial data flow if it senses CTS inactive (high logic). CTS is set inactive while power saving and set active while running at full speed and ready to receive. Since power saving exits at least every 2 seconds, DTE shall be capable to cache up to 2 seconds of information flow (host polling mode). System waits on a software timer for 5000 frames (23.077 sec) after the last valid character received, allowing immediate response, before re-enter power saving. Hardware flow control is currently supported only on ASC0, not on ASC1. 5.11 Security 3-2000733 supports a security module that prevents uncontrolled installation/updates of software on delivered products. The IMEI (International Mobile Equipment Identity) cannot not be changed after the ME’s final production process: the protection of the IMEI shall resist tampering, i.e. manipulation and change by any means (e.g. physical, electrical and software). The security module provides the required measures to fulfill these IMEI protection requirements. For protection against flash tampering, the system uses a unique Chip Identification Number for encryption and authentication of valid flash memory images.
