General Description
The EM78P134N is an 8-bit microprocessor designed and developed with low-power and high-speed
CMOS technology. It has an on-chip 1K×13-bit Electrical One Time Programmable Read Only Memory
(OTP-ROM). It provides three protection bits to prevent intrusion of user’s OTP memory code as well as
from unwanted external accesses. Several code option bits are available to meet user’s requirements.
With its enhanced OTP-ROM feature, the EM78P134N provides a convenient way of developing and
verifying user’s programs. Moreover, this OTP device offers 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.
