Description

This HT82A821R is an 8-bit high performance RISC-like microcontroller designed for USB Speaker product applications. They combines a 16-bit DAC, USB transceiver, SIE (Serial Interface Engine), audio class processing unit, FIFO, 8-bit MCU into a single chip. The DAC in the HT82A821R is operating at the 48kHz sampling rate. They has a digital programmable gain amplifier. The gain range is from -32dB to +6dB.

The HT82A821R has a Human Interface Device function that allows a user to control the playback volume at the device side. They also can mute the analog output signal by the operation of HID buttons.
