2. Baseband Circuit description of SGH-E350

1. PCF50603 (U400)

1.1. 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).

1.2. Backlight Brightness Modulator

The Backlight Brightness Modulator (BBM) contains a programmable Pulse-width modulator (PWM) and FET to

modulate the intensity of a series of LED? s or to control a DC/DC converter that drives LCD backlight.

This phone (SGH-E350) use PWM control to contrast the backlight brightness.

1.3. 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. LCD Connector

LCD is consisted of main LCD(color 6.5K TFT LCD).

Chip select signals in the U305, LCD_CS, can enable LCD. BACKLIGHT signal enables white LED of main LCD. These

signal is from U400.

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".


Circuit Description

4. Key

This is consisted of key interface pins KEY_ROW(0:4) and KEY_COL(0:4) in PCF5213EL1. These signals compose the

matrix. Result of matrix informs the key status to key interface in the PCF5213EL1. 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 sixteen

blue LEDs.

key LED use the 3.3V LDO(U606) for a supply voltage. KEY_LED_ON signal enables eight white LED.

"FLIP" informs the status of slide (up or down) to the PCF5213EL1. This uses the hall effect IC, EM-1681-FT(U607).

A magnet under LCD enables EM-1681-FT.

5. EMI ESD Filter(F501,F502)

This system uses the EMI ESD filter, F501,F502 to protect noise from IF CONNECTOR part.

6. IF connetor(IFC500)

It is 18-pin connector. They are designed to use VBAT, V_EXT_CHARGE, USB_D+, +VBUS, USB_D-, TXD1, RXD1,

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

7. Battery Charge Management IC(U501)

A complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries is used.

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.

8. Audio

HFR_P and HFR_N from PCF5213EL1 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. YMU762 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 40 tones by stereophonic hybrid synthesizer.

YMU762 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.

9. Memory(U303)

This system uses Samsung's memory, KAP17SG00A. The KAP17SG00A is a Multi Chip Package Memory which

combines 256Mbit Synchronous Burst Multi Bank NOR Flash Memory and two 512Mbit OneNAND Flash and

128Mbit Synchronous Burst UtRAM.

It has 16 bit data line, HD[1~16] which is connected to PCF5213EL1 and MV3018SAQ, also has 24 bit address lines,

HA[1~24]. There are 3 chip select signals, CS0n_FLASH, CS4n_NAND, and CS1n_RAM.

In the Writing process, WEn is fallen to low and it enables writing process to operate. During reading process,

OEn is fallen to low and it enables reading process to operate. Each chip select signals in the PCF5213EL1 choose

different memories.

MV3018SAQ provides rich video functions up to 30-frame display with minimized tasks in the handset main processor

as well as hardware based real-time JPEG compression and decompression. MV3018SAQ directly transmits and

previews the RGB data to the LCD graphic memory by processing the sensor output data according to the

handset's command. It can save the raw RGB data up to VGA resoultion into its image buffer and allows the

host processor to download with scalable sized compressed data.
