Description

EM78P417/8/9N is 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology. It is equipped with a 4K*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 EM78P417/8/9N.
