) MOSEL VITELIC INC. Preliminary MSU3022 August 1997 60" Voice Smart with LCD General Description The MSU3022 is a monolithic talking microcomputer that can memorize voice up to 60 seconds using MOSEL qualified coding method (MPCM-5). It's an integration of traditional 4-bit microcotroller and voice chip with minimal external components. LCD driver and miscellaneous interface by 20-bit i/o are provided for versatile applications. With more than bit 10K bits ROM/RAM inside, this chip meets every intelligent novelty. Customer requested function and voice data will be built in by changing masks during fabrication. Hardware Features m@ Low current consumption @ Working at 2.4V through 6.0V ™@ Maximal function with minimal cost @ Precise voice sample rate 8 KHz is provided. ™ Current output could drive 8 ohm speaker with a ill Auto ramp up and ramp down. transistor, Vout could drive buzzer directly. m Halt mode is provided. ™ The voice content is stored up to 60 seconds at Very low current consumption at Halt mode.
