      Aplus’ aIVR  is a 8-bit CPU based Voice chip series.  It is fabricated with Standard CMOS process with embedded voice
      storage memory. It can store from 42sec voice message with 4-bit ADPCM compression at 6KHz sampling rate. 8-bit PCM
      is also available as user selectable option to improve sound quality.Depending on IC body,there are up to twelve programmable
      I/O pins.  Key trigger and Parallel CPU trigger mode can be configured according to different application requirement.  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.
