SNC735 16-bit Voice Processor 1. INTRODUCTION SNC735 is a 32mins two-channel speech/melody and 4-channel wave-table melody voice chip. It based on reduced 16-bit fixed-point DSP architecture. SNC735 provides user some necessary and efficient DSP instructions. Furthermore, SNC735 provide one 10-bit PWM and one 10-bit DA converter to driving speaker for speech/melody output. User can select PWM or DA by programming DA/PWM control register, and only one function can be active at the same time. 2..
