Built-in EPROM Version

The built-in EPROM version can be used for program development only. Use them only for program

development and implementation evaluation.

Sunlight and fluorescent light include light that may erase the information programmed in the built-

in PROM. When using the EPROM version in the read mode, be sure to cover the transparent glass

portion with a seal.

This seal to cover the transparent glass portion is prepared by Mitsubishi. Be careful not to bring

the seal into contact with the microcomputer lead wires when covering the portion with the seal

because this seal is made of metal (aluminum).

Before erasing data, clean the transparent glass. If any finger stain or seal adhesive is stuck to the

transparent glass, this prevents ultraviolet rays from passing, thereby affecting the erase characteristic

adversely.
