GPFA64C1中文资料8-Bit CPU, 8-CH melody sound controller数据手册Generalplus规格书

描述 Description

The GPFA64C1 is a fuly CMOS integrated circuit. It uses advanced design and process technology to combine an 8-bit RISC program ROM, 224 bytes working SRAM, timer/counter and I/Os interface in a single chip. The sound processing logic is a unique design to achieve high quality melody effect. It can simulate all types of musical instruments by programming the tone ROM and controlling the envelope slope of each channel. Each channel can also be defined as a speech channel to generate percussion, animal sound, gunshot, explosion, and other special sound effects in PCM along with the main music rhythm.
