The EM78F544N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology and high noise immunity. It has an on-chip 4K x 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 EM78F544N 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 their development code.
