HT82A821R
USB Audio MCU
Rev. 1.10
1
June 29, 2007
General Description
This HT82A821R is an 8-bit high performance
RISC-like microcontroller designed for USB Speaker
product applications. The HT82A821R 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 HT82A821R is operating
at the 48kHz sampling rate. The HT82A821R has a digi-
tal programmable gain amplifier. The gain range is from
32dB to +6dB.
The HT82A821R has a Human Interface Device func-
tion that allows a user to control the playback volume at
the device side. The HT82A821R also can mute the an-
alog output signal by the operation of HID buttons.
