INTRODUCTION The SNC729 is a simply chip base on new DSP technology. SNC729 provide simply and easy control functions for system manufactory. SNC729 also is a high performance voice IC. That is built-in 64K word high speed ROM, and by different model to built-in 64K word ~ 960K words low speed ROM, the maximum program size is full ROM size include high-speed and low-speed ROM. The SNC729 have three timer, one real time clock and one watchdog timer and built-in a hi-performance software synthesizer to provide lot of voice effects, such as hi-decompression engine to support from 1.5Kbps ~ 32Kbps compression rate for speech and music, multi-channel voice synthesizer to provide 12-channel wave table melody. 2.
