Features
Single power supply can operate at 2.4V
through 6V.
Current output can drive 8 ohm speaker with a
transistor, Vout can drive buzzer directly.
The voice content is stored for 7-12
seconds for 13-24 seconds (21000h) including
mute and should be multiples of 200h.

Interrupt function (INTP) stops the audio output
at once.
An LED function with 3Hz flash is provided to
tell the audio status.
A STOP pulse comes out when audio signal is
finished.
CDS input interface with 10ms debounce is
provided for trigger pin, REP pin and INTP pin.
Repeat pin was provided to keep audio output
repeating.
Built-in power on play function and is
programmable.
