描述 Description

SNC735 is a 32mins two-channel speech/melody and 4-channel wave-table melody voicechip. It based on reduced 16-bit fixed-point DSP architecture. SNC735 provides usersome necessary and efficient DSP instructions. Furthermore, SNC735 provide one 10-bitPWM and one 10-bit DA converter to driving speaker for speech/melody output. Usercan select PWM or DA by programming DA/PWM control register, and only one functioncan be active at the same time.
