SNC7x5 series ia a series of 2-channel speech / melody with 4-channel wave-table melody voice chip which is based on reduced 16-bit fixed-point DSP architecture. SNC7x5 series provides a 10-bit PWM / 10-bit DA converter (programmable) to driving speaker for speech / melody output.

SNC710 is a 16-bit fixed-point DSP architecture voice engine with a built-in Sonix's mask ROM interface. SNC710 executes the external mask ROM which stores user's program and voice data.
