Voice speech melody ic cob module

AP89170 is high performance voice OTP, fabricated with standard CMOS process with embedded 4MB EPROM. It can store up to 170 sec voice massage with 4-bit ADPCM compression at 6KHz sampling rate. 8-bit PCM is also available as user selectable . Three triggers modes, simple Key trigger mode and Parallel CPU trigger mode and CPU serial command mode, facilitate difference user interface. User selectable triggering and output signal option provide maximum flexibility to various applications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct driving output minimize the number of external components
