AU7842 USB HOST MP3/WMA DECODER SOC
1. Overview
A highly integrated SOC for MP3/WMA player, AU7842 integrates MCU,
MP3/WMA decoder, USB Host controller, SD/MMC card controller, a 16-bit audio
decoder and an IR decoder in a single chip. Compared with traditional flash-MP3
player, AU7842 offers a lower cost, lower power consumption, flexible and more
powerful Host MP3/WMA player solution.

3. Pin Description
AU7842 is a CMOS device. Floating level on input signals causes unstable device
operation and abnormal current consumption. Pull-up or Pull-down resistors should be used
appropriately for input or bidirectional pins.
