LC6529F

Ordering number : EN*5117 CMOS LSI LC6529N, LC6529F, LC6529L 4-Bit Microcomputer for Small-Scale Control Applications Preliminary Overview The LC6529N/F/L provides the basic architecture and instruction set of the Sanyo LC6500 Series of 4-bit singlechip microcomputers in a version specially for small-scale control applications involving circuits built with standard logic elements, applications using simple, comparatorbased voltage or phase detectors, or other applications controlling a limited number of controls. The LC6529F is a replacement for the former LC6529H. (Certain functions differ, however.) The N (medium-speed) and L (powersaving) versions are new additions to the lineup. Choice of clock oscillator options to match system specifications — Oscillator circuit options: 2-pin RC oscillator circuit (N and L versions) or 2-pin ceramic oscillator circuit (N, F, and L versions) — Frequency divider options: Built-in 1/3 and 1/4 frequency dividers that eliminate the need for external frequency dividers Features Power-saving CMOS design (Standby mode accessed with HALT instruction included.) Memory: 1 kilobyte of 8-bit ROM and 64 words of 4-bit RAM Instruction set: 51-member subset of LC6500 standard complement of 80 instructions (L version) Wide range of operating voltages: 2.2 to 6.0 V (F version) 0.92 µs/3.0 V instruction cycle time Flexible I/O ports Four ports with up to 16 lines — Bidirectional I/O ports: 12 Dedicated input ports: 4 (These double as com...
