Combination of voice building blocks to extend playback duration.

Table entries are available for voice slice combinations.

Five standard triggering modes are available (controlled by software):

Key Trigger

Sequential

CPU Parallel

CPU Serial

MP3

Voice section trigger options: Edge / Level; Hold / Un-hold; Retrigger / Non-retrigger.

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

2.7V ~ 3.6V single power supply and < 15uA stand-by current.

PWM Vout1 and Vout2 drive speaker directly.

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

RSTB provides external controlled reset to the chip.

DESCRIPTION

Aplus’ aMTPxxM series is multi-time program voice IC.

It is fabricated with Standard CMOS process with

voice storage flash memory. Offer five trigger modes: Key trigger mode, sequential mode, CPU parallel

mode, CPU serial mode and MP3 mode, facilitate different user interface. User selectable triggering and

output signal options provide maximum flexibility to various applications. External resistor ROSC control

oscillator, 8-bit resolution current mode D/A output and PWM direct speaker driving minimize the number of

external components.
