GPFA64F1中文资料8-Bit CPU, 8-CH melody sound controller数据手册Generalplus规格书

描述 Description

The GPFA64F1, a fully CMOS integrated circuit, adopts advanced design and process technology to combine an 8-bit RISC processor, an 8-channel music synthesizer, 64K bytes 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.  Every channel can also be defined as a speech channel to produce percussion, animal sounds, gun-fire, explosions and other special sound effects in PCM to accompany the main music rhythm.
