HT82A821R General Description
This HT82A821R is an 8-bit high performance RISC-like microcontroller designed for USB Speaker product applications. The HT82A821R combines a 16-bit DAC, USB transceiver, SIE (Serial Interface Engine), audio class processing unit, FIFO, 8-bit MCU into a single chip. The DAC in the HT82A821R is operating at the 48kHz sampling rate. The HT82A821R has a digital programmable gain amplifier. The gain range is from -32dB to +6dB.
The HT82A821R has a Human Interface Device function that allows a user to control the playback volume at the device side. The HT82A821R also can mute the analog output signal by the operation of HID buttons.
HT82A821R Maximum Ratings
Supply Voltage .................VSS-0.3V to VSS+6.0V
Input Voltage........................VSS-0.3V to VDD+0
Total Power Dissipation .........................500mW
