GENERAL DESCRIPTION
Firmware can be upgradeable from USB port. For storage, NAND-type Flash is supported. It can support with 8-bit, 16-bit dat a bus wid th NAND Flash or it can use 2 pieces 8-bit NAND Flash to achieve high bandwid th. It can use up to 4 pieces to exp and memory storage capacity. 8 bit Error detection and correction is generated for on board NAND Flash. A1569 supports card reader function for SD/MMC card. Microprocessor is included for user interface. It support s serial interface for dif ferent LCD panels. Push bottoms and remote control pad are also provided for user control. Many GPIO pins are for more flexible system design. DC-DC is integrated. It cont ains two channels for dif ferent system volt ages. It can convert power from USB bus power or it can use battery and then boost volt age. Low battery voltage detection is included in this chip. This SoC Chip includes a high performance stereo FM transmitter designed for portable multimedia systems. It consists of a digital modulator for generating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air.
