 The Main System contains basic circuit blocks, such as Processor(TCC7801), SDRAM, Flash Memory,
Power Block, Audio DAC, etc., and function blocks, such as Bluetooth Block, 24pin I/O, and etc. The display is
connected to a 2-inch TFT LCD.
 Serial Interfaces between ICs are implemented with various Protocols throughout the System.
A host processor (TCC7801) UART is used to implement CODEC and FM Tuner features.
 The interface between the Bluetooth Module and the Host Processor is achieved through UART, and the audio DAC
achieves mode setting and data transfer through I2C and I2S, respectively.
 Power can be turned On and Off with the Power S/W located at the top of the set. Either the built-in battery or the
power adapter can be used for power supply. The power adapter is capable of 5V input. Power from the power adapter
is used to recharge the battery at AAT2550 and generates power for the system (3.0V, 1.2V).
