Description
A highly integrated SOC for MP3 player, AU6210K integrates MCU, FM receiver, MP3 decoder, OTG, SD/MMC card controller, SARADC, Audio DAC, segment LED/LCD display driver, RTC, IR decoder, touch key and key tone generator in a single chip, AU6210K offers low cost, low power consumption, flexible and more powerful host MP3 player solution.
A USB Host MP3 Decoder SoC (System-on-a-Chip) is an integrated circuit that combines the functionality of a USB host controller and an MP3 audio decoder in a single chip. This type of SoC is designed specifically for devices that require the ability to decode and play MP3 audio files from USB storage devices.
The USB host controller portion of the SoC allows the device to act as a host, enabling it to connect and communicate with USB flash drives, external hard drives, or other USB storage devices. It provides the necessary hardware and software interfaces to handle USB communication protocols and file system access.

Pinouts
AU6210K 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.
