HT82A850R Description
The HT82A850R is an 8-bit high performance RISC-like microcontroller designed for USB Phone product applications. The HT82A850R integrates a 16-bit PCM ADC and an 8-bit MCU into a single device. The DAC in the HT82A850R operates at a sampling rate of 48/8kHz and the 16-bit PCM ADC operates at a frequency of 8kHz for the Microphone input.
