Flash Media Pla yer with FM T ransmitter SoC
A1569 integrates high bandwid th USB2.0 for 480 mbp s transfer rate. With high
bandwidth, user can easily download music and upload voice recordings within minutes.
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. This device
