aP89341 series high performance Voice OTP is fabricated with Standard CMOS process with embedded 8M bits EPROM.
It can store up to 341sec voice message with 4-bit ADPCM compression at 6KHz sampling rate. 8-bit PCM is also available
as user selectable option.Three trigger modes,simple Key trigger mode,Parallel CPU trigger mode and CPU serial command
mode, facilitate different user interface. User selectable triggering and output signal options provide maximum flexibility to
various applications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker driving
output minimize the number of external components. PC controlled programmer and developing software are available.
