DESCRIPTION
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.
