CMOS IC
LC651432N/F/L, 651431N/F/L
Four-Bit CMOS Microcontrollers for
Small-Scale Control Applications
Overview
The LC651431N/F/L and LC651432N/F/L are the small-
scale control models in Sanyo’s LC6500 Series of 4-bit
microcontrollers and feature the same basic architecture
and instruction set. These microcontrollers are appropriate
for a wide range of applications, from applications that
require only a limited number of circuits and controls and
were previously implemented in standard logic to larger
application such as audio equipment, including tape decks
and disc players, office equipment, communication
equipment, automotive equipment, and home appliances.
Furthermore, since these products have equivalent basic
functions (although there are differences in some functions
and characteristics) and are pin compatible with the earlier
LC6543N/F/L and LC6546N/F/L products, they can be
used to replace those devices.
Features
• Fabricated in a CMOS process for low power operation
(Standby mode can be controlled by CPU instructions.)
• ROM/RAM
LC651432N/F/L
—ROM: 2 K × 8 bits, RAM: 128 × 4 bits
LC651431N/F/L
—ROM: 1 K × 8 bits, RAM: 64 × 4 bits
• Instruction set: The 80-instruction set common to the
whole LC6500 Series
• Wide operating supply voltage range of 2.2 to 6.0 V
(L versions)
• Instruction cycle time of 0.92 µs (F versions)
• On-chip serial I/O function
• Highly flexible I/O ports
Number of ports
— 7 ports (Up to 25 pins)
All ports
— Can be used for either input or output
— Voltage handling capability (input and output):
15 V maximum (For open-drain specification ports)
— Output current: 20 mA maximum sink current
(Capable of directly driving an LED.)
I/O port options to match application requirements:
— Open-drain output and pull-up resistor specification:
Can be specified for all ports in bit units.
— Output level at reset specification: Either a high or
low level can be specified for ports C and D in 4-bit
units each.
• Interrupts
Timer overflow vector interrupt (can also be tested by
CPU instructions)
INT pin or serial I/O full/empty vector interrupt (can
also be tested by CPU instructions)
• Stack levels: 4 levels (also used by interrupts)
• Timers: 8-bit programmable timer with 4-bit prescaler
• Clock oscillator options to match application
requirements:
Oscillator circuit option:
— Two-pin RC oscillator (N and L versions)
Two-pin ceramic oscillator or single external clock
input pin (N, F, and L versions)
— Divider circuit option: No divider, built-in divide-
by-three circuit, built-in divide-by-four circuit
(N and L versions)
• Continuous square-wave output with a period 64 times
the cycle time.
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.
