Semiconductor Bussiness Headquarters TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN 4-Bit Microcomputer for Small-Scale Control Applications LC6529N, LC6529F, LC6529L Overview The LC6529N/F/L provides the basic architecture and instruction set of the Sanyo LC6500 Series of 4-bit single- chip microcomputers in a version specially for small-scale control applications involving circuits built with standard logic elements, applications using simple, comparator- based 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 (power- saving) versions are new additions to the lineup. 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 comparator inputs.) — I/O voltage limit: max. +15 V (open-drain configuration) — Output current: max. 20 mA sink current (capable of directly driving an LED) Choice of options to match system specifications — Choice of open-drain or pull-up resistor output configurations at the bit level for all ports — Choice of reset output levels for Ports C and D in groups of 4 bits each Port E configurable as four comparator inputs • Stack: Four levels • Timers: 4-bit prescaler plus 8-bit programmable counter • Comparators: 4 channels (2 reference levels) Separator reference level for each channel pair — Feedback resistor option for choice of input with or without hysteresis • 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 |
