MSu001/u001T MOSEL VITELIC February 1996 20" VOICE SMART General Description The MSu001 is a monolithic talking microcomputer that can memorize voice up to 22 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 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.

PWR Signal AUDIO PWR BUSY 1. When PWR is high , MSu001 audio output signal will stay at approx. 2.4V even there is no audio output . 2. When PWR is low , MSu001 audio output signal will stay at GND level when there is no audio output . 3. For eliminating the "pop" noise purpose , PWR should be at high level when a sound section is played over , and also at high level in between two sound sections . 4. For energy saving purpose , PWR should not always stay at high level , since there will be a hundred-mA current consumption when PWR is high . So it should go to low level when its not needed .
