General Description
The HT82A851R is an 8-bit high performance RISC-like
microcontroller designed for wireless USB Phone prod-
uct applications. The HT82A851R combines a SPI,
USB transceiver, SIE (Serial Interface Engine), audio
class processing unit, FIFO and an 8-bit MCU into a sin-
gle chip. The play frequency in the HT82A851R oper-
ates at a sampling rate of 48/8kHz. HT82A851R has a
digital programmable gain amplifier. The gain range is
from 32dBto+6dB.FortheIsochronousinput,thedigi-
tal gain range is from 0dB to 19.5dB.
