Features, Applications

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 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: V (F version) s/3.0 V instruction cycle time Flexible I/O ports Four ports with 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
