EM78P156K

EM78P156K

The EM78P156K is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 1024 x 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. Three Code option words are also available to meet user's requirements.
With enhanced OTP-ROM features, the EM78P156K 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 your development code.
