 In the Main System, the Processor (S5L8700), SDRAM, Flash Memory, Power Block, Audio DAC and others have a
basic circuit block and include the FM-Tuner function block. The display connects with the 1.8 inch TFT LCD.
 The IC Serial Interface covers the whole system and has a variety of protocols. First use the host processor (S5L8700)
UART and implement the CODEC and FM Tuner functions.
 The audio DAC use to I2C, I2S to achieve Mode Setting and data transmission separately.
Li-Polymer
Batt.
600mAh  The power is turned on or off by the Power S/W on the right side of the set. Power is possible through the internal
battery or the adapter, and 5V input is possible with the adapter. Power through the adapter charges the battery at
AAT2550, and system power (2.8V, 1.2) is made.
