I2S
■ The main system comprises MPU (TCC79x), NAND Flash Memory, SDRAM (64MByte 32bit), BT+FM IC (BCM2048),
Audio Codec (WM1800) and POWER IC (MAX8819).
■ The TCC79x, which is the main chipset, plays a major role by connecting to other chipsets.
■ The POWER IC MAX8819 receives power from the USB/5V adaptor or the battery, and supplies it to the system after
converting it to a suitable voltage for the system (5V, 3.2V, 1.8V, 1.2V), charges the Li-poly Battery and turns on the
LCD Backlight.
■ The Audio Codec (WM1800) is interconnected with the main chipset, 12S and 12C interface to output the sound of the
earphones and external speaker. It also supports functions such as a Bluetooth headset and hands free, interconnected
with the BT+FM IC.
