APT310 Description:
    APT310 is a 10 Sec Easy Use Speech IC .
    It Support PWM or DAC voice output with high quality speech , There are 10 second Voice Length under 6 KHz sampling and 4 bit hardware compression. Its internal built-in a oscillator for system clock without an external resistor.
    Maximum 63 voice groups. One Group contain several steps(voice section ); Maximum 700 steps for all the Groups. Each Step can be define Trigger Mode, Output Status, Voice Section, Mute length, I/O Type & Simple Programming Function.
    User can select 8bit / 5bit / 4bit data compression. Support three mode trigger IC (Stand Alone, Serial Trigger Mode, CPU Command Mode ). Easy use development system is for function selection and voice combination . PC download the ROM code by the USB Port .
