General Description

EM78P259N and EM78P260N are 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology. 

It is equipped with a 2K*13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). 

With its OTP-ROM feature, it is able to offer a convenient way of developing and verifying your programs. 

Moreover, it provides a protect bit to guard against code intrusion, as well as 3 Code Option words to accommodate your requirements. 

Furthermore you can take advantage of ELAN Writer to easily write your development code into the EM78P259N and EM78P260N.
