1) PSC2106
1. Power Management
Seven low-dropout regulators designed specifically for GSM applicationspower the terminal and help ensure optimal system performance and longbattery life.A programmable boost converter provides support for 1.8V, 3.0V, and 5.0VSIMs, while a self-resetting, electronically fused switch supplies power toexternal accessories. Ancillary support functions, such as an LED driver andtwo call-alert drivers, aid in reducing both board area and systemcomplexity.A three-wire serial interface unit(SIU) provides access to control and
configuration registers. This interface gives a microprocessor full control ofthe PSC2106 and enables system designers to maximize both standby andtalk times.Supervisory functions. including a reset generator, an input voltage monitor,and a thermal monitor, support reliable system design. These functionswork together to ensure proper system behavior during start-up or in theevent of a fault condition(low microprocessor voltage, insufficient batteryenergy, or excessive die temperature).
2. Battery Charge Management
A battery charge management block provides fast, efficient charging of asingle-cell Li-ion battery. Used in conjunction with a current-limited voltagesource and an external PMOS pass transistor, this block safely conditionsnear-dead cells and provides the option of having fast-charge and top-offcontrolled internally or by the system's microprocessor.
3. Backlight LED Driver
The backlight LED driver is a low-side, programmable current sourcedesigned to control the brightness of the keyboard and LCD illumination.The driver is enabled by EN_LED, and its current setting is determined byLED[0:2]. Provided EN_LED is '1', the driver can be programmed to sinkfrom 12.5mA to 100mA in 12.5mA steps. LED_DRV is capable of sinking100mA at a worst-case maximum output voltage of 0.6V. For efficient use,the LEDs is connected between the battery and the LED_DRV output.

4. Vibrator Motor Dirver
The vibrator motor driver is a low-side, programmable voltage sourcedesigned to drive a small dc motor that silently alerts the user of anincoming call. The driver is enabled by EN_VIB, and its voltage setting isdetermined by VIB[0:2]. Provided EN_VIB is a logic 1, the driver can beprogrammed to maintain a motor voltage of 1.1V to 2.5V in 20mV steps andwhile sinking up to 100mA. For efficient use, the vibrator motor should beconnected between the main battery and the VIB_DRV output.
2) Connector
1. LCD Connector
LCD is consisted of main LCD(color 65K STN LCD) and small LCD(4-grayLCD). Chip select signals of EMI part in the trident, CLCD_EN_FO andGLCD_EN_FO,can enable Each LCD. LED_EN_FO signal enables white LED of main LCDand EL_EN_FO signal enables EL of small LCD.These two signals are from IO part of the DSP in the trident. RST signalfrom 2006 initiates the initial process of the LCD.16-bit data lines(D(0)_FO~D(15)_FO) transfers data and commands to LCDthrough emi_filter. Data and commands use A(2)_FO signal. If this signal ishigh, Inputs to LCD are commands. If it is low, Inputs to LCD are data. Thesignal which informs the input or output state to LCD, is required. But thissystem is not necessary this signal. So CP_WEN_FO signal is used to writedata or commands to LCD.Power signals for LCD are V_bat and V_ccd.SPK1P and SPK1N from CSP1093 are used for audio speaker. AndVIB_EN_FO from enables the motor.
2. JTAG Connector
Trident has two JTAG ports which are for ARM core and DSPcore(DSP16000). So this system has two port connector for these ports.Pins' initials for ARM core are 'CP_' and pins' initials for DSP core are'DSP_'.CP_TDI and DSP_TDI signal are used for input of data. CP_TDO andDSP_TDO signals are used for the output of the data. CP_TCK andDSP_TCK signals are used for clock because JTAG communication is asynchronous. CP_TMS and DSP_TMS signals are test mode signals. Thedifference between these is the RESET_INT signal which is for ARM coreRESET.

These are connected toBACKLIGHT signal in the PSC2106.This signal enables LEDs with current control. FLIP_SNS informs the statusof folder (open or closed) to the trident. This uses the hall effect IC,A3210ELH.A magnet under main LCD enables A3210ELH which is on the key FPCB.

6) Trident
Trident is consisted of ARM core and DSP core. It has 20K*16bits RAM144K*16bits ROM in the DSP. It has 4K*32bits ROM and 2K*32bits RAM in theARM core. DSP is consisted of timer, one bit input/output unit(BIO), JTAG, EMIand HDS(Hardware Development System). ARM core is consisted of EMI,PIC(Programmable Interrupt Controller), reset/power/clock unit, DMA controller,TIC(Test Interface Controller), peripheral bridge, PPI, SSI(Synchronous SerialInterface), ACC(Asynchronous communications controllers), timer, ADC,RTC(Real-Time Clock) and keyboard interface.DSP_AB[0~8], address lines of DSP core and DSP_DB[0~15], data lines ofDSP core are connected to CSP1093. A[0~20], address lines of ARM core andD[0~15], data lines of ARM core are connected to memory, LCD and YMU759.ICP(Interprocessor Communication Port) controls the communication betweenARM core and DSP core.CSROMEN, CSRAMEN and CS1N to CS4N in the ARM core are connected toeach memory.

charging(CHG_DET, CHG_STAT0), SIM_RESET and FLIP_SNS with which weknows open.closed status of folder. It has JTAG control pins(TDI/TDO/TCK) forARM core and DSP core. It recieves 13MHz clock in CKI pin from externalTCXO and receives 32.768KHz clock from X1RTC. ADC(Analog to DigitalConvertor) part receives the status of temperature, battery type and batteryvoltage. And control signals(DSP_INT, DSP_IO and DSP_RWN) for DSP core areused. It enables main LCD and small LCD with DSP IP pins.
7) CSP1093
CSP1093 integrates the timing and control functions for GSM 2+ mobileapplication with the ADC and DAC functions. The CSP1093 interfaces to thetrident, via a 16-bit parallel interface. It serves as the interface that connectsa DSP to the RF circuitry in a GSM 2+ mobile telephone. DSP can load 148bits of burst data into CSP1093’s internal register, and program CSP1093’sevent timing and control register with the exact time to send the burst. Whenthe timing portion of the event timing and control register matches the internalquarter-bit counter and internal frame counter, the 148 bits in the internalregister are GMSK modulated according to GSM 2+ standards. The resultingphase information is translated into I and Q differential output voltages that canbe connected directly to an RF modulator at the TXOP and TXON pins. TheDSP is notified when the transmission is completed. For receiving basebanddata, a DSP can program CSP1093’s event timing and control register with theexact time to start receiving I and Q samples through TXIP and TXIN pins.When that time is reached, the control portion of the event timing and controlregister will start the baseband receive section converting I and Q samplepairs. The samples are stored in a double-buffered register until the registercontains 32 sample pairs. CSP1093 then notifies the DSP which has ample timeto read the information out before the next 32 sample pairs are stored. Thevoice band ADC converter issues an interrupt to the DSP whenever it finishesconverting a 16-bit PCM word. The DSP then reads the new input sample andsimultaneously loads the voice band output DAC converter with a new PCMoutput word. The voice band output can be connected directly to a speaker viaAOUTAN and AOUTAP pins and be connected to a Ear-mic speaker viaAOUTBN and AOUTBP pins.
8) X-TAL(13MHz)
This system uses the 13MHz TCXO, TCO-9141B, Toyocom. AFC control signalform CSP1093 controls frequency from 13MHz x-tal. It generates the clockfrequency. This clock is fed to CSP1093,Trident,YMU759 and Silab solution.
