General Description

This HT82A822R is an 8-bit high performance

RISC-like microcontroller designed for USB Speaker

product applications. The HT82A822R combines a

16-bit DAC, USB transceiver, SIE (Serial Interface En-

gine), audio class processing unit, FIFO, 8-bit MCU into

a single chip. The DAC in the HT82A822R is operating

at the 48kHz sampling rate. The HT82A822R has a digi-

tal programmable gain amplifier. The gain range is from

-32dB to +6dB.

The HT82A822R has a Human Interface Device func-

tion that allows a user to control the playback volume at

the device side. The HT82A822R also can mute the an-

alog output signal by the operation of HID buttons.
