Overview

The LC86E4448 is a CMOS 8-bit single chip microcontroller with UVEPROM for the LC864400 series.

This microcontroller has the function and pin description of the LC864400 series mask ROM version, and the 48K-byte EPROM. The program data is rewritable. It is suitable for developing programs.

Features

(1) Option switching by EPROM data

The option function of the LC864400 series can be specified by the EPROM data.

The functions of the trial pieces can be evaluated using mass production board.

(2) Internal EPROM capacity : 49152 bytes (for Program)

: 8192 x 12-bit (for Character data)

(3) Internal RAM capacity : 384 bytes

The LC86E4448 contains 49152-byte EPROM and 386-byte RAM, each size is the maximum capacity of the LC864400

mask-ROM series. Be careful of ROM size.
