DESCRIPTION
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 10 to 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.
