General Description

The HT82A832R is an 8-bit high performance RISC-like

microcontroller designed for USB Phone product

applications. The HT82A832R combines 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. For the

DAC, the HT82A832R has a digital programmable gain

amplifier. The gain range is from -32dB to +6dB. For the

ADC input, the digital gain range is from 0dB to 19.5dB.
