LC6529N Datasheet | SANYO

Overview The LC6529N/F/L provides the basic architecture and instruction set of the Sanyo LC6500 Series of 4-bit singlechip microputers in a version specially for small-scale control applications involving circuits built with standard logic elements, applications using simple, paratorbased 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 plement 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 parator inputs.) - I/O voltage limit: max. +15 V (open-drain configuration) - Output current: max. 20 m A 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 parator inputs - Stack: Four levels - Timers: 4-bit prescaler plus 8-bit programmable counter - parators: 4 channels (2 reference levels) Separator reference level for each channel pair - Feedback resistor option for choice of input with or...
