      aP89085 series high performance Voice OTP is fabricated with Standard CMOS process with embedded 2M bits EPROM. 
      It can store up to 85 sec 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.
