General Description  
The HT82A836R is an 8-bit high-performance RISC  
microcontroller designed for USB phone product appli-  
cations. To ensure a high level of functional integration  
for USB phone applications, this 8-bit microcontroller in-  
cludes important features such as 16-bit PCM A/D Con-  
verter, USB transceiver, Serial Interface Engine, audio  
class processing unit, m 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 ampli-  
fier with a range of -32dB to +6dB. The digital gain  
range of the ADC input is from 0dB to 19.5dB.
