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). Most of the necessary circuit are
built in like oscillator, ROM, DAC and interface logic. Versatile functions can be performed with minimum
external components. Customer voice data will be edited and built in by MOSEL writer in an instant time
base.
