    Aplus’ aIVR3K is a 8-bit CPU based Voice chip series.  It is fabricated with Standard CMOS process with
    embedded voice storage OTP memory.  It can store 21sec 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 eight programmable I/O pins.  Key trigger and Parallel CPU trigger
    mode can be configured according to different application requirements. User selectable triggering and
    output signal options provide maximum flexibility to various applications.   Fully integrated system oscillator,
    power-on reset,  8-bit current mode D/A output and PWM direct speaker driving output to minimize external
    components count. Two level volume control for PWM direct speaker driving output.
