LC6514B

Single-Chip 4-bit Microcontroller (Low-Threshold Input, On-Chip FLT Driver)

SANYO -> Panasonic 

Ordering number:ENN1802C

LC6514B

Single-Chip 4-bit Microcontroller

(Low-Threshold Input, On-Chip FLT Driver)

Overview

Package Dimensions

The LC6514B is a microcontroller with FLT drivers. It is

identical with the LC6510C in the internal architecture and

instruction set. Since the normal/low-threshold level of in-

put port A can be selected by option and the on-chip pull-

down resistor can be bitwise connected to the FLT driver

by option, the number of external parts used in the user

equipment can be minimized, reducing the cost consider-

ably.
