ADPCM SOUND CONTROLLER Preliminary General Description The A132000 is a fully CMOS integrated circuit. It uses advanced design and process technology to bine 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 pression, LCD display, functional control and others. Features n 8-bit RISC controller n Provide 2Mbit ROM area n Provide maximum 2K bytes ROM area for program data n 80bytes working SRAM n Audio output, audio output current: 5 m A n 8-bit timer/counters with 8-bit programmable prescaler n Provide 8-bit current output D/A n Provide 20 general I/Os n Provide 4 output only drive LEDs n Key wake up function n Low voltage reset function n Crystal Operation or Built-in 4M Hz RC-Oscillator Operation n ESD, insensitive n Two-level hardware push/pop stack n Only 33 single word instruction to learn n Wide operation range:2.7V-5.5V n Software audio for speech and melody n Provide 60 seconds playing of audio or speech voice n Built-in watch dog timer n Clock stop mode n ADPCM encoding/decoding method n Power-On Reset (POR) Application Field n Intelligent education toys ex.
