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 up to 6 seconds
and can be separated to 9 sections.
Nine trigger input pins are provided. Each
trigger pin can access a phrase instead of
simple section. A phrase is composed of one
or more than one section(s) and called a
section - combination of sections.
Total section number of all phrases is up to 64.
Total duration of all sections with mute is up
to 24 seconds.
Interrupt function (INTP) stops the audio output
at once.
Playall function (OKY) plays all 9 phrases one
by one by single trigger.
Sequential function (OKY): one trigger plays
next phrase of 9 phrases circularly.

Description
The MSS0605 is a monolithic CMOS VLSI ASIC that can memorize voice up to 6 seconds using
MOSEL qualified coding method (MPCM). It can play 9 phrases instead of 9 simple sections. Most
of the necessary circuit are built in like oscillator, ROM, DAC and interface logic. 2 LEDs and
separate option setting is provided . Customer voice data will be edited and built in by mask
programming during the device fabrication.
