      aP89021 high performance Voice OTP is fabricated with Standard CMOS process with embedded 512K bits EPROM. It can 
      store up to 21sec voice message with 4-bit ADPCM compression at 6KHz sampling rate.8-bit PCM is also available as user 
      selectable option.Two trigger modes,simple Key trigger mode and Parallel CPU trigger 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.
