Preliminary
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.
Hardware Features
Low current consumption Maximal function with minimal cost Current output could drive 8 ohm speaker with a transistor, Vout could drive buzzer directly.
The voice content is stored up to 120 seconds at 6 KHz (B0000h) and can be separated to 256 sections.
Duration of each section can be different and is multiples of 100h.
Duration of section with appended memory-less mute is up to 40 seconds (100000h).
Each trigger can access a sentence, up to 256 sentences could be access.
1024 entry count are provided.
