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.
