EM78P259N/260N
8-Bit Microcontroller with OTP ROM
1 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.
2 Features
