EM78P417N/418N/419N
8-Bit Microprocessor with OTP ROM
1 General 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.
