Description
The MSSI121/241/241B is an one time programmable CMOS VLSI ASIC that can memorize voice for 7-12 / 13-24 seconds using 6-bit MOSEL qualified coding method (MPCM).
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 SI121 ( 13-24 for SI241/241B ) including mute and is single section / phrase and single trigger. Automatic power down. A phrase is composed of repetitive sections. 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.
