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 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.
鈥?Choice of clock oscillator options to match system
specifications
鈥?Oscillator circuit options: 2-pin RC oscillator circuit
(N and L versions) or 2-pin ceramic oscillator circuit
(N, F, and L versions)
鈥?Frequency divider options: Built-in 1/3 and 1/4
frequency dividers that eliminate the need for
external frequency dividers
Features
鈥?Power-saving CMOS design (Standby mode accessed
with HALT instruction included.)
鈥?Memory: 1 kilobyte of 8-bit ROM and 64 words of 4-bit
RAM
鈥?Instruction set: 51-member subset of LC6500 standard
complement of 80 instructions
鈥?(L version) Wide range of operating voltages:
2.2 to 6.0 V
鈥?(F version) 0.92 碌s/3.0 V instruction cycle time
鈥?Flexible I/O ports
Four ports with up to 16 lines
鈥?Bidirectional I/O ports: 12
Dedicated input ports: 4 (These double as
comparator inputs.)
鈥?I/O voltage limit: max. +15 V (open-drain
configuration)
鈥?Output current: max. 20 mA sink current (capable of
directly driving an LED)
Choice of options to match system specifications
鈥?Choice of open-drain or pull-up resistor output
configurations at the bit level for all ports
鈥?Choice of reset output levels for Ports C and D in
groups of 4 bits each
Port E configurable as four comparator inputs
鈥?Stack: Four levels
鈥?Timers: 4-bit prescaler plus 8-bit programmable counter
鈥?Comparators: 4 channels (2 reference levels)
Separator reference level for each channel pair
鈥?Feedback resistor option for choice of input with or
without hysteresis
