1. PCF50601

1.1. Power Management
Ten 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, and 5.0V 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 sy stem complexity.
I2C BUS serial interface provides access to control and configuration registers. This interface gives a microprocessor full
control of the PCF50601 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).

1.2. LCD Backlight Brightness Controler (MAX1574)
The Backlight Brightness is controled by Main chip(OM6357_7) through the MAX1574 charge pump.

The MAX1574 charge pump drives three white LED's with regulated constant current for uniform
intensity.

The MAX1574 uses an external resistor to set the full scale 100% LED current. An enable input
(EN-"BACKLIGHT") is used for simple on/off control or can be pulsed repeatedly to set lower LED current in multiple
steps down to 5%. Once the desired brightness is set, the MAX1574 maintains constant LED current as long as EN is
kept high. If EN is kept low for more than 2ms, the MAX1574 enters shutdown.
When the LEDs are enabled by driving EN high, the MAX1574 goes through soft-start, bringing the LED current up to
I

. Dimming is then done by pulsing EN low (500ns to 500µs pulse width). Each pulse reduces the LED current by

2-1. LCD Connector

LCD is consisted of main LCD(color 65K TFT LCD).
Chip select signals in the
LCD. This signal is from IO part of the DSP in the U300(Main Chip). "LCD_RESET" signal initiates the Reset process
of the LCD.
16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD through by pass capacitor. 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 "VBAT and "VDD2".
"SPK_P" and "SPK_N" from OM6357 are used for audio speaker. And "VDD_VIB" from PCF50601 enables the motor.

2-3. IrDA

This system uses IrDA module, HSDL_3208, Agilent's. This has signals, "IrDA_DOWN" (enable signal), "RXD0" (input
data) and "TXD0" (output data). These signals are connected to OM6357. A power signals, "VDD2" is used for circuit
and LED.

U400

2-4. Key

This is consisted of key interface pins among OM6357, KBIO[0~7]. These signals compose the matrix. Result of matrix
informs the key status to key interface in the OM6357. Power on/off key is seperated from the matrix. So power on/off
signal is connected with PCF50601 to enable PCF50601.

Key LED is consisted of four white LED for sub key and six white LED for main key. Key LED use the "BLVDD"

supply voltage. Main key LED is controlled by the "VDD_KEY" supply voltage.

"FLIP" informs the status of folder (open or closed) to the OM6357. This uses the hall effect IC, EM-1681-FT.
A magnet under main LCD enables EM-1681-FT.

2-5. EMI ESD Filter

This system uses the EMI ESD filter, EMIF09 to protect noise from IF CONNECTOR part.

It is 18-pin connector. They are designed to use VBAT, +DCVOLT, TXD0, RXD0, RTS0, CTS0, JIG_REC,
CHARGER_OK, RXD1, TXD1 and GND. They connected to power supply IC, microprocessor and signal processor IC.

3. Battery Charge Management

A complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries.
If TA connected to phone, "+DCVOLT" 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.

Circuit Description

YMU765MA5 is a LSI for portable telephone that is capable of playing high quality music by utilizing FM synthesizer
and ADPCM decorder that are included in this device. As a synthesis, YMU765MA5 is equipped 32 FM voices and 32
Wave Table voices. Since the device is capable of simultaneously generating up to synchronous with the play of the FM
synthesizer, various sampled voices can be used as sound effects.
Since the play data of YMU765MA5 are interpreted at anytime through FIFO, the length of the data(playing period) is
not limited, so the device can flexiblysupport application such as incoming call melody music distribution service.
The hardware sequencer built in this device allows playing of the complex music without giving excessive load to the
CPU of the portable telephones. Moreover, the registers of the FM synthesizer can be operated directly for real time
sound generation, allowing, for example, utilization of various sound effects when using the game software installed in the
portable telephone.
YMU765MA5 includes a speaker amplifier with high ripple removal rate whose maximum output is 580mW
(SPVDD=3.6V). The device is also equipped with conventional function including a vibartor and a circuit for controlling
LEDs synchornous with music.
For the headphone, it is provided with a stereophonic output terminal.
For the purpose of enabling YMU765MA5 to demonstarte its full capablities, Yamaha purpose to use "SMAF:Synthetic
music Mobile Application Format" as a data distribution format that is compatible wiht multimedia. Since the SMAF takes
a structure that sets importance on the synchronization between sound and images, various contents can be written into it
including incoming call melody with words that can be used for traning karaoke, and commercial channel that combines
texts, images and sounds, and others. The hardware sequencer of YMU765MA5 directly interprets and plays blocks
relevant to systhesis (playing music and reproducing ADPCM with FM synthesizer) that are included in data distributed in
SMAF.
