MSU3132 lcd-less 90" voice smart mosel vitelic inc. 1/1 (pid 261* -3) 07/98 specifications subject to change without no tice, contact your sales representatives for the most recent information. july 1998 general description the MSU3132 is a monolithic talking microcomputer that can memorize voice up to 90 seconds using mosel qualified coding method (mpcm-5). it's an integration of traditional 4-bit microcotroller and voice chip with minimal external components. 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 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 90 seconds at 6 khz (81000h) 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. working at 2.4v through 6.0v precise voice sample rate 8 khz is provided. auto ramp up and ramp down. halt mode is provided. very low current consumption at halt mode. no lcd driver provided built-in clock generator built-in doubler, halver, tripler internal program rom : 1024 x 15 bits; internal program ram : 64 x 4 bits internal stack ram: 4x10 bits. two 4-bit input ports two 4-bit input/output ports one 4-bit output port preliminary development supports development tools are provided software / hardware programming guide is provided evaluation chip u3040 is to be available soon software features 76 instructions, in 39 mnemonics 4-level subroutine nesting (also used for interrupt) two external factors (int, s&m) for interrupt two internal factors (timer, divider) for interrupt sample applications handy game without lcd versatile timepiece without lcd talking timer without lcd intelligent calculator without lcd smart stationery without lcd talking home electronics without lcd msm9068 msm9088 msm9018 developing card program code emulation board 120" sound emulation board talking education kit withot lcd mask options either open or hold transistor on s port & m port either pull down or pull up on interrupt switch either leading edge or trailing edge on interrupt edge either power back-up activated or not when power on either with reset or not when power on either 8 ms or 2 ms chattering removal time on s port & m port either slow (by 15.625 ms) or fast (by 224.14 us) set time timer either fast system clock ( fosc) or slow system clock ( fosc / 2) either rosc or 32768 hz crystal to play voice development supports pid321 voice smart programmer's guide pid345 voice smart ice m9068 user's manual
