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 341 sec 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.
