Embedded 8-bit MCU.

10 sec voice duration at 6 KHz sampling with 4-bit ADPCM compression.

Combination of voice building blocks to extend playback duration.

Table entries are available for voice block combinations.

User selectable PCM or ADPCM data compress.

Voice Group Trigger Options: Edge / Level; Hold / Un-hold; Retrigger / Non-retrigger.

Programmable I/Os, Timer Interrupt and Watch Dog Timer.

Built-in oscillator with fixed Rosc, software control sampling frequency

2.2V – 3.6V single power supply and < 5uA low stand-by current.

PWM Vout1 and Vout2 drive speaker directly [ only for DIP16/SOP16 ].

D/A COUT with ramp-up ramp-down option to drive speaker through an external BJT.

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.
