Circuit Description
2-2. Baseband Circuit description of SGH-D600 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 LCD is consisted of main LCD(color 262K TFT LCD). Chip select signals in the U301, LCD_MAIN_CS, can enable LCD. BACKLIGHT signal enables white LED of main LCD. 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_WRB" signal is used to write data or commands to LCD. Power signals for LCD are "VDD_IO_HIGH".
2-2-3. Key This is consisted of key interface pins KEY_ROW(0:4) and KEY_COL(0:4) in PCF5212EL1. These signals compose the matrix. Result of matrix informs the key status to key interface in the PCF5212EL1. 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 LEDs for sub key and twelve white LEDs for main key. White LED for sub key use the VBAT voltage. "SLIDER_KEY_ON" signal enables Transistor for sub key backlight. Main key LED use the
3.3V LDO for a supply voltage. KEY_LED_ON signal enables eight white LED.
"FLIP" informs the status of slide (open or closed) to the PCF5213EL1. This uses the hall effect IC, EM-1681 A magnet under LCD enables EM-1681.

2-2-4. EMI ESD Filter This system uses the EMI ESD filter, U500 to protect noise from IF CONNECTOR part.
2-2-5. IF connetor 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, HFK_SPK, HFK_MIC and GND. They connected to power supply IC, microprocessor and signal processor IC.
2-2-6. Battery Charge Management A 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.
2-2-7. Audio HFR_P and HFR_N from PCF5212El1 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. AK4642 is 16-bit stereo audio CODEC with a built-in microphone - Amplifier and Headphone - Amplifier. I2S signals from CL8522S5 are decoded with audio analog signals. SAPA1D2-24ELP amplify these signals and deliver to stereo speakers.
2-2-8. Memory This system uses Samsung's memory, KBH10PD00M-D414. The KBH10PD00M is a Multi Chip Package Memory which combines 256Mbit Synchronous Burst Multi Bank NOR Flash Memory and two 1Gbit OneNAND Flash and 256Mbit Synchronous Burst UtRAM. It has 16 bit data line, HD[1~16] which is connected to PCF5212 and CL8522S5, also has 24 bit address lines, HA[1~24]. There are 3 chip select signals, CS0n_FLASH, CS4n_NAND, and CS1n_RAM. In the Wrting 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 PCF5212 choose different memories.
