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 10 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. 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.

Note:
1. C1 is capacitor from 0.1uF to 2.2uF depends on the kind of Vdd source and sound loudness.
E.g. If COUT is used, C1 can be 0.1uF. However, if PWM direct drive speaker is used, C1
should be at least 2.2uF
2. Rb is base resistor from 120 Ohm to 390 Ohm depends on Vdd value 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 and support sampling rate up to 14KHz
5. For sampling rate higher than 14KHz, smaller value of Rosc should be used.
