Part no. : AP89K_DB24 2. PCB SIZE : 41 x 31 mm 3. PCB NO. : 4D02 4. VDD = 2 ~ 5V 5. PWM & DAC 6. SBT PIN : For Key mode one key sequential trigger 1~1024(max.) groups ** Two options for ROSC : 1. Compiling Internal Resistor ( ROSC-INT ) : Do not need any resistors. 2. Compiling External Resistor ( ROSC-EXT ) : Using fixed 68KOhm resistor. ** For PWM output, Only required one 104 capacitor on the board for playback. ** There are several different function for OUT1-OUT3.
