DESCRIPTION
Aplus’ aIVR8511 is a 8-bit MCU based Voice chip. It is fabricated with Standard CMOS process
with embedded voice storage memory. It can store 85sec 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 eleven 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. Two levels volume control for PWM speaker direct drive is
available.
