LM6416E NMOS 4-Bit Single-Chip Microcomputers IC DIP-28S

Description

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 21 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. Features Single 5 V power supply with wide voltage operating range (4.5 to 6.5 V) N-channel E/D MOS CMOS/TTL compatible 1K bytes of ROM, 64 words (by 4 bits) of RAM Wide range of settings for programmable timer 17 I/O pins that can interface directly with 12 V equipment. All ports can withstand 15 V. Normal current output ports provide 20 mA. 1 Kbyte versions/instruction and pin-compatible High-speed operation LM6417 minimum cycle time: 4 us at 4.5 V Instruction set 65 instructions Applications Consumer equipment (logic replacement, sub-CPU of multi-CPU system) Other small to mid-scale equipment where low cost is needed (control) Specifications: Type No.: LM6416 ROM (bits): 1k x 8 bits RAM Cycle (bits): 64 x 4 bits Timers: 4 us Ports Withstan
