The EM78P1523S are 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The devices have on-chip 1024 or 13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). They provide 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 EM78P152/3S 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. You can avail of the ELAN Writer to easily program your development code.
