HT82A836R -- USB Audio MCU

The HT82A836R is an 8-bit high-performance RISC microcontroller designed for USB phone product applications. To ensure a high level of functional integration for USB phone applications, this 8-bit microcontroller includes important features such as 16-bit PCM A/D Converter, USB transceiver, Serial Interface Engine, audio class processing unit, u law Compander, 6-channel 12-bit ADC, 2-channel PWM and FIFO.
The DAC in the HT82A836R operates at a sampling rate of 48kHz/8kHz and the 16-bit PCM ADC operates at frequency of 8kHz/16kHz for the Microphone input, with the options selected using software. The integrated DAC also includes a digitally programmable gain amplifier with a range of -32dB to +6dB. The digital gain range of the ADC input is from 0dB to 19.5dB.
