FEATURES
z z z z z z z z z Stand CMOS process. Embedded 1M bit EPROM. 40 Sec Voice Length at 6 KHz sampling and 4‐bit ADPCM compression. Built‐in oscillator to control sampling frequency without an external resistor . Maximum 64 voice groups. One groups contain several steps(voice section) ;Maximum 700 steps for all the groups. User selectable 8bit / 5bit / 4bit data compression. 2 input pin(TG1&TG2) and 6 user selectable input or output pin (TG5 & TG6 & TG7 & TG8 & TG11 & TG12). Two triggering modes are available by whole chip option during voice compilation ‐ Key Trigger Mode – Up 64 Voice Groups are trigger by TG1 & TG2 & TG5~TG8 & TG11 & TG12 ‐ Serial Trigger Mode‐Combinations of TG1 and TG5 to trigger maximum 32 Voice Groups. ‐ CPU Serial Trigger Mode – user commands are clocked serially into the chip to control the playback of chip. z z z z z z z z Voice Group Trigger Options: Edge/LEVEL; Hold/Un‐hold; Retrigger/Non‐retrigger. User selectable 50us (@8KHz sampling rate) or 10ms (@8KHz sampling rate) Debounce Time in all of three trigger Modes. Two user programmable outputs for FLASH(0.75Hz/1.5Hz/3Hz/6Hz) or BUSY(High/Low). Support Power‐on play. 2.6 ~ 5.0V;Wide range single power supply and <1uA low stand‐by current. PWM pwm1 and pwm2 drive speaker directly. D/A PWM2 to drive speaker through an external BJT or OP.
