Four-Bit CMOS Microcontrollers for
Small-Scale Control Applications
Preliminary
Overview
The LC651154N/F/L and the LC651152N/F/L are the
small-scale control application versions of Sanyo’s
LC6500 series of 4-bit single-chip CMOS
microcontrollers, and feature the same basic architecture
and instruction set. These microcontrollers include an 8-
input 8-bit A/D converter and are appropriate for use in a
wide range of applications, from applications with a small
number of circuits and controls that were previously
implemented in standard logic to applications with a larger
scale such as home appliances, automotive equipment,
communications equipment, office equipment, and audio
equipment such as decks and players. Also note that since
these ICs provide the same basic functions (certain
functions and specifications do differ) as, and are pin
compatible with the earlier LC651104N/F/L and
LC651102N/F/L, they can replace those ICs in most cases.

(Open-drain specification C, D, E, and F ports
only)
· Output current: 20 mA (maximum) sink current
(Are capable of directly driving an LED.)
— Support options to match application system
specifications
A. Open-drain output, internal pull-up resistor
specification: All ports, in bit units
B. Output level at reset specification: Ports C and D
can be specified to go to the high or low level in
4-bit units.
• Interrupt function
— Timer interrupts through an interrupt vector (Can be
tested under program control)
— INT pin and serial I/O full/empty interrupts through
an interrupt vector (Can be tested under program
control)
• Stack levels: 8 (Shared with the interrupt system.)
• Timers: 4-bit variable prescaler and 8-bit programmable
timers
• Clock oscillator options that match a wide range of
system specifications
— Oscillator circuit options:
Two-pin RC oscillator (N and L versions)
Two-pin ceramic oscillator (N, F, and L versions)
— Clock divider circuit options:
No divider, built-in divide-by-3, built-in divide-by-4
(N and L versions)
• Continuous square wave output (with a period 64 times
the cycle time)
• A/D converter (successive approximation)
— 8-bit precision with 8 input channels
• Watchdog timer
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.
