  General Description

The EM78F542N is an 8-bit microprocessor designed and developed with low-power, highspeed
CMOS technology, and high noise immunity. It has an on-chip 2K×13-bit Electrical Flash
Memory. 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 EM78F542N 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.
You can avail of the ELAN Writer to easily program your development codes.
