1 7/11/2011 ? Description AK040H is a

40 Sec Easy Use Speech IC .It Support PWM or DAC voice output with high quality speech , There are

40 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 . ? Functions ? MAX voice file :
