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.
