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.

configurations such as pure input, input with pull-up, input with pull-down and output. The
programmable I/O pins set up will take effect immediately after chip RESET is applied.
Pins for memory programming are: VDD, VDDA, VSS, PB0, PB1, OSC, VOUT2 and RSTB.

Note for COUT speaker drive:
1. C1 must be connected as close to the chips VDD and VSS pins as possible.
2. Rb is base resistor from 120 Ohm to 390 Ohm depends on value of VDD and transistor gain.
3. Tr is an NPN transistor with beta larger than 150, e.g. 8050D.
4. Rosc = 610K Ohm with Vdd=3.0V can support sampling rate up to 14KHz.
5. For sampling rate higher than 14KHz, smaller value of Rosc should be used.
