Circuit Description
2-2. Baseband Circuit description of SGH-X700 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).
-
Pulse-Width Modulator The Backlight Brightness Modulator (BBM) contains a programmable Pulse-width modulator (PWM) to modulate the intensity of a series of LED's or to control a DC/DC converter that drives LCD backlight. This phone is using PWM control to modulate the LCD backlight brightness.
-
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 X700 has just one 1.9" TFT LCD. 16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD. There are couple of control signals such as RS, CS, RD, WR, etc. RS stands for "Register Select pin." When RS = 0, data can be written to the index register or status can be read, and when RS = 1, an instruction can be issued or data can be written to or read from RAM. Read or write operation is selected according to RD/WR signals. The data is received when the R/W bit is 0, and is transmitted when the R/W bit is 1. At the falling edge of CS input, serial data transfer is
initiated. On the other hand, at the rising edge of CS input, the data transfer is ceased.
2-2-3. Key Key recognition part is consisted of 8 ports from PCF5213EL1. KEY_ROW(0:4) & KEY_COL(0:4) These signals performs with the matrix. Any input from the matrix informs the key status to key interface in the PCF5213EL1. Power on/off key is independent of the matrix. Therefore, 'power on/off' signal is directly connected with PCF50603 to turn PCF50603 on. 3.3V LDO(U700) enables Key LED on. Key LED consists of 12 LEDs. It is controlled by "Key_led_on" signal. 2-2
