General Description
The EM78F64xN/54xN Series are 8-bit microprocessors designed and developed with low-
power, high-speed CMOS technology, and high noise immunity. Each these MUCs is equipped
with an on-chip 1/2/4K×13-bit and 8Kx15-bit Electrical Flash Memory, but only the EM78F64xN
is embedded with 256 or 128×8-bits in-system programmable EEPROM. Each 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 EM78F64xN/54xN MUCs provide a convenient way
of developing and verifying user’s programs. Moreover, the Flash-ROM device offers the
advantages of easy and effective program updates with development and programming tools.
You can take advantage of ELAN’s Writer to easily program your development codes.
