 The Main System consists of such basic circuit blocks as Processor (TCC7801), SDRAM (32Mbit), Flash Memory,
Power Block, and Audio DAC, and includes FM_Tuner, Bluetooth Block, and LCD Block.
 Serial interfaces between the IC's are implemented with various protocols throughout the system.
The Host Processor (TCC7801) and the UART are used to implement the Audio DAC and the FM Tuner, the interface
between the Bluetooth Module and the Host Process is accomplished by the UART, and the Audio DAC accomplishes
mode setting and data transfer through I2C and I2S, respectively.
 Power can be turned on and off with the power switch on the side of the device. Either the built-in battery or the power
adapter can be used for power supply. The power adapter is capable of 5V input. The power from the power adapter
charges the battery at AAT2550. Four (4) different voltages required are 2.8V (Main), 1.07V (CPU Core), 1.8 (SDRAM
Memory), and 3.1V (WQVGA LCD).
