(This specification is subject to change without further notice)

General Description

The EM78F651N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology

and high noise immunity. It has an on-chip 1K

×13-bit Electrical Flash Memory and 128×8-bit in system programmable

EEPROM. It provides three protection bits to prevent intrusion of user’s Flash memory code. Twelve Code option bits

are also available to meet user’s requirements.

With its enhanced Flash-ROM feature, the EM78F651N provides a convenient way of developing and verifying user’s

programs.

Moreover, this Flash-ROM device offers the advantages of easy and effective program updates, using

development and programming tools. User can avail of the ELAN Writer to easily program his development code.
