This chip is fully integrated GSM GPRS quad-band transceiver with transmit baluns(balanced-unbalanced matching devices)

, loop filters and most of the passive component in it.

And also fully integrated fractional N RF synthesizer with AFC control possibility, RF VCO with integrated supply

regulator. Semi integrated reference oscillator with integrated supply regulator.

RF Receiver front-end amplifies the GSM850, DCS1800 and PCS1900 aerial signal, convert the chosen channel

down to a low IF of 100kHz.

In IF section, further amplifies the wanted channel output level to the desired value and rejects DC.

2-2-1. PCF50603 (U400)

— Power Management

Eight low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal

system performance and long battery life. A programmable boost converter provides support for 1.8V, 3.0V SIMs,

while a self-resetting, electronically fused switch supplies power to external accessories. Ancillary support functions,

such as RTC module and High Voltage Charge pump, Clock generator, aid in reducing both board area and system

complexity.

I2C BUS serial interface provides access to control and configuration registers. This interface gives a microprocessor

full control of the PCF50603 and enables system designers to maximize both standby and talk times.

Supervisory functions. including a reset generator, an input voltage monitor, and a temperature sensor, support reliable

system design. These functions work together to ensure proper system behavior during start-up or in the event of a

fault condition(low microprocessor voltage, insufficient battery energy, or excessive die temperature).

— Clock Generator

The Clock Generator (CG) generates all clocks for internal and external usage. The 32.768 kHz crystal oscillator

provides an accurate low clock frequency for the PCF50603 and other circuitry.

2-2-2. LCD ConnectorLCD is consisted of main LCD(color 262K TFT LCD) and sub LCD(color 65K OLED LCD)

Chip select signals in the U305, LCD_MAIN_CS, LCD_SUB_CS can enable LCD. BACKLIGHT signal enables white

LED of main LCD. These signal is from U200.

16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD. Data and commands use "RS" signal. If this signal

is high, Inputs to LCD are commands. If it is low, Inputs to LCD are data. The signal which informs the input or output

state to LCD, is required. But this system is not necessary this signal. So "L_WR" signal is used to write data or

commands to LCD. Power signals for LCD are "VDD_IO_HIGH".

2-2-3. BLUE TOOTHThis system uses Blue Tooth module, UGNZ3, ALPS. This has signals, "BT_INT"(Interrupt signal), "RXD2"(input data)

and "TXD2"(output data), PCM control signal(DCL[PCMCLK], DO[PCM_IN], DU[PCM_OUT], FSC[PCM_SYNC]) These

signals are connected to PCF5212EL1EL1.

2-2-4. KeyThis is consisted of key interface pins KEY_ROW(0:4) and KEY_COL(0:4) in PCF5212EL1EL1. These signals compose

the matrix. Result of matrix informs the key status to key interface in the PCF5212EL1EL1. Power on/off key is

seperated from the matrix. So power on/off signal is connected with PCF50603 to enable PCF50603. Key LED is

consisted of 12 white LEDs for main key. Main key LED use the 3.3V LDO for a supply voltage. KEY_LED_ON

signal enables 12 white LED.

"FLIP" informs the status of folder (open or closed) to the PCF5212EL1EL1. This uses the hall effect IC, EM-1681-FT.

A magnet under LCD enables EM-1681-FT.

AUX_ON, EXT1, EXT2, and GND. They connected to power supply IC, microprocessor and signal processor IC.

2-2-7. Battery Charge ManagementA complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries.

If TA connected to phone, "V_EXT_CHARGE" enable charger IC and supply current to battery.

When fault condition caused, "CHG_ON" signal level change low to high and charger IC stop charging process.

2-2-8. AudioHFR_P and HFR_N from PCF5212EL1EL1 are connected to the main speaker via analog switches. MIC_P and MIC_N

are connected to the main MIC as well. EAR1 is the source of External Speaker. YMU765 is a synthesizer LSI for

mobile phones. This LSI has a built-in speaker amplifier for outputting sounds that are used by mobile phones in addition

to game sounds and ringing melodies that are replayed by a synthesizer.

The synthesizer section adopts “stereophonic hybrid synthesizer system”that are given advantages of both FM

synthesizers and Wave Table synthesizers to allow simultaneous generation of up to 32 FM voices and 32 Wave

Table voices.

It provides simultaneous generation of up to 64 tones by stereophonic hybrid synthesizer.

YMU765 has built a speaker amplifier of which maximum out is 580 mW at SPVDD=3.6V in this device.

There is Stereophonic analog output for Headphone.
