EM78P447N

EM78P447N is an 8-bit microprocessor with low-power and high-speed CMOS technology and high noise immunity. It has a built-in 4K x 13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides three protection bits to prevent intrusion of user's OTP memory code. Seven option bits are also available to meet user's requirements.

With its enhanced OTP-ROM features, the EM78P447N provides a convenient way of developing and verifying user's programs. Moreover, this OTP device offers the advantages of easy and effective program updates, using development and programming tools. User can avail of the ELAN Writer to easily program his development code.
