      Aplus’ aIVR341N is a 8-bit MCU based Voice chip. It is fabricated with Standard CMOS process with embedded voice storage
      memory.It can store 341sec 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. There are upto fifteen 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, 9-bit resolution current mode 
      D/A output and PWM direct speaker driving minimize the number of external components.  Volume control for both DAC and
      VOUT output is available.
