The EM78F562N is an 8-bit microprocessor designed and developed with low-power, high-speed 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 EM78F562N provides a convenient way of developing and verifying user's
programs. Moreover, this Flash-ROM device offers the advantage of easy and effective program updates, using
development and programming tools. User can avail of the ELAN Writer to easily program his development code.
