HT82A832R Overview
The HT82A832R is an 8-bit high performance RISC-like microcontroller designed for USB Phone product applications. The HT82A832R bines a 16-bit PCM ADC, USB transceiver, SIE (Serial Interface Engine), audio class processing unit, FIFO and an 8-bit MCU into a single chip. The DAC in the HT82A832R operates at a sampling rate of 48kHz/8kHz and the 16-bit PCM ADC operates at 8kHz for the Microphone input.
