APT305 Description:
APT305 is a 5 Sec Easy Use Speech IC .
It Support PWM voice output with high quality speech , There are 5 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 12 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 two 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 USB Port .
