HT82A851R Overview
The HT82A851R is an 8-bit high performance RISC-like microcontroller designed for wireless USB Phone product applications. The HT82A851R bines a SPI, USB transceiver, SIE (Serial Interface Engine), audio class processing unit, FIFO and an 8-bit MCU into a single chip. The play frequency in the HT82A851R operates at a sampling rate of 48/8kHz.
