LM6417E NMOS 4-Bit Single-Chip Microcomputers IC

Overview

The LM6413/6416/6417 NMOS 4-bit single-chip micro- computers are optimized for consumer equipment. They are compact and powerful, yet have an excellent cost/performance ratio.
These microcomputers contain a high-speed 4-bit parallel-processing CPU core, 1K bytes of ROM, 64 words (by 4 bits) of RAM, a programmable timer, clock generator, and 17 I/O pins that can withstand up to 15 V and can interface directly with 12 V equipment.
These microcomputers have 65 instructions. Their capabilities include subroutine nesting, a wide range of timer settings, automatic stepping of page settings, and pseudo-interrupt functions.
These microcomputers are ideal for logic replacement in consumer equipment and for sub- CPUs in multi-CPU systems.
