The EM78P153K is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 1024′13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a protection bit to prevent intrusion of user s OTP memory code. Fifteen Code option bits are also available to meet user’s requirements.

With enhanced OTP-ROM features, the EM78P153K 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. You can avail of the ELAN Writer to easily program your development code.
