The SNC749 is a simply chip base on new DSP technology. SNC749 provide simply and
easy control functions for system manufactory. SNC749 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, 448K words low speed ROM, the maximum program size is full ROM size include
high-speed and low-speed ROM. The SNC749 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.
