HE NMOS 4-Bit Single-Chip Microcomputers =e The LM6413/6416/6417 NMOS 4-bit single-chip micro- 3 computers are optimized for consumer equipment. They ys are compact and powerful, yet have an excellent cost/per- formance ratio. These microcomputers contain a high-speed 4-bit paral- ota i Zo. lel-processing CPU core, 1K to 2K bytes of ROM, 64 to 128 Se tf eo words (by 4 bits) of RAM, a programmable timer, clock gen- eatt erator, and 17 to 21 V/O pins that can withstand up to 15 V ar and can interface directly with 12 V equipment. i eee ag ‘ ~ itt! The LM6413/6416/6417 microcomputers have 65 Bee ’ tt 27] instructions. Their capabilities include subroutine nesting, a eS tt! ae wide range of timer settings, automatic stepping of page lee yt! arn settings, and pseudo-interrupt functions.
