Circuit Description
2-2. Baseband Circuit description of SGH-E730 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 Connector LCD 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 TOOTH This 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. Key This 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. 2-2
