EM78F641N

The EM78F641N 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 features, the EM78F641N 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. Users can avail of the ELAN Writer to easily program his development code.
