■ The main system includes the basic circuit block with the processor (TCC7801), SDRAM, flash memory, power block,
audio DAC etc. and the function block with the Bluetooth block, 24pin I/O, etc. The display is connected to the 2 inch
TFT LCD.
■ The IC serial interface is made of the various protocols covering the entire system. It first uses the host processor
(TCC7801) UART to make the CODEC and FM tuner functions.
■ The interface between the Bluetooth Module and the processor is created through the UART, and the audio DAC
creates the mode setting and data transmission through the I2C and I2S.
■ It is possible to turn the power on and off by the Power S/W on the right side of the set. Power is possible through
the internal battery or the power adapter; the adapter has a 5V input. Power from the adapter charges the battery at
AAT2550 and creates the system power (3.0V, 1.2V)
