SC080G are single-chip voice synthesizing CMOS IC. They are embedded EPROM architecture, and OTP (One Time Programmable) Speech chip,   Each body has one input and three I/O pins. Through accurate internal oscillation, external Rosc is unnecessary. It Support  PWM or DAC output for voice. Thus any external component is not required.Maximum 62 voice groups.Serial trigger mode maximum 62 voice groups ,moble One Group contain several steps(voice section ); Maximum 700 steps for all the Groups. Maximum 80 seconds Voice. Each Step can be define Trigger Mode, Output  Status,  Voice  Section,  Mute  length,  I/O  Type  &  Simple Programming  Function.   Support  three  mode  trigger  IC  (Stand  Alone,  Serial Trigger Mode ). Easy use development system is for function selection and voice combination . PC download the ROM code by the OTP_Writer.
