HT82A834R General Description

The HT82A834R is an 8-bit high performance RISC-like microcontroller designed for USB Phone product applications. The HT82A834R 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 HT82A834R operates at a sampling rate of 48kHz/8kHz and the 16-bit PCM ADC operates at 8/16kHz for the Microphone input. For the DAC, the HT82A834R 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.

HT82A850R General 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. The DAC in the HT82A850R also has a digital programmable gain amplifier, whose gain ranges from -32dB to +6dB. For the ADC input, the digital gain range is from 0dB to 19.5dB.
