A132000

ADPCM SOUND CONTROLLER

General Description

The A132000 is a fully CMOS integrated circuit. It uses advanced design and process technology to combine an 8-bit

RISC processor with program/data ROM, 80-byte working SRAM, timer/counter, I/O, built-in oscillator and audio current

mode D/A. The high speed RISC processor can implement software based audio processing, data compression, LCD

display, functional control and others.
