Preliminary
General Description
The MSU30x2 is a monolithic talking microcomputer that can memorize voice up to 60/90/120 seconds
using MOSEL qualified coding method(MPCM). It's an integration of traditional 4-bit microcomputer and
voice chip with minimal external components. LCD driver and miscellaneous interface are provided
for versatile applications. With more than bit 10K ROM/RAM inside, this chip meets every intelligent
novelty. Customer requested function and voice data will be built in by changing masks during fabrication.
