¡ Semiconductor

MSM81C55-5RS/GS/JS

Differences between MSM81C55-5 and MSM81C55

1) Manufacturing Process

These devices use a 3 m Si-CMOS.

2) Design

These devices use the same chip. However, different outgoing inspection standards are used for

these devices separately.

3) Electrical Characteristics

''Oki's '96 Data Book for MICROCONTROLLER'' describes that the MSM81C55-5 satisfies the

electrical characteristics of the MSM81C55.

As shown above, the devices can be replaced without any trouble.
