Overview

The LC72E32 microcontroller is an on-chip UVEPROM version of the LC7232N single-chip microcontroller plus PLL product. The LC72E32 has the same functions and pin assignment as the LC7232N mask ROM version. Its on-chip EPROM has an 8-Kbyte capacity and a 4-Kword by 16-bit organization. Since programs can be rewritten multiple times, the LC72E32 is optimal for program development.

Features

• Options can be switched with EPROM data

The LC7232N option functions can be specified with

EPROM data. This allows the actual mass production

printed circuit board to be used for test product

evaluation.

• 8 Kbytes (with a 4-Kword by 16-bit organization) of

UVEPROM on chip

The LC72E32 includes 8 Kbytes of UVEPROM

(ultraviolet erasable EPROM) on chip.

• The pin arrangement is identical to that of the LC7232N

mask ROM version, i.e., pin compatibility is

maintained.
