EM78P211/2N
8-Bit Microprocessor with OTP ROM
1
General Description
EM78P211N and EM78P212N are 8-bit microprocessors designed and developed with low-power and high-speed CMOS
technology. Each device in the series has as an on-chip 2K×13-bit Electrical One Time Programmable Read Only Memory
(OTP-ROM). Each provides a protection bit to prevent intrusion of user’s OTP memory code. Two Code option bits are
also available to meet user’s requirements.
With its enhanced OTP-ROM features, each device provides a convenient way of developing and verifying user’s
programs. Moreover, this OTP devices offer 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.
