TG020is a20 Sec Easy Use Speech IC .It SupportPWMor DACvoice output with high quality speech ,There are 20 second Voice Length under 6 KHz sampling and 4 bit hardware compression. Its internal built-in a oscillator for system clockwithout an external resistor. Maximum 63 voice groups. One Group contain several steps(voice section );Maximum 700 stepsfor all the Groups.Each Stepcan be defineTrigger Mode,Output Status,Voice Section,Mute length,I/O Type&Simple Programming Function. User can select8bit / 5bit / 4bitdata 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 .
