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
ADCinput,thedigitalgainrangeisfrom0dBto19.5dB.
