SNC725中文资料16-bit Voice Processor数据手册Sonix规格书

描述 Description

SNC725 is a 16mins two-channel speech/melody and 4-channel wave-table melody voicechip. It based on reduced 16-bit fixed-point DSP architecture. SNC725 provides usersome necessary and efficient DSP instructions. Furthermore, SNC725 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.
