Circuit Description
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.

MV3018B(Camera DSP Chip) controls the communication between ARM core and DSP core. OEn, WEn control the access of memory. KROW, and KCOL recognize the key string input status. It has J-TAG control pins (TDI/TDO/TCK) for ARM and DSP core. J-SEL signal controls different access to ARM and DSP core. ADC(Analog to Digital Convertor) receives the condition of temperature, battery type and battery voltage. 11. TCO-5871U(26MHz)(U102) This system uses the 26MHz TCXO, TCO-5871U, Toyocom. AFC control signal form PCF5213EL1 controls frequency from 26MHz x-tal. It generates the clock frequency. This clock is connected to PCF5213EL1, YMU762 and HD155166.
12. Camera DSP(MV3018SAQ)(U305) 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. It utilizes 16 bit data bus for communication with the main processor, including bus interface types.
