Product Summary

The EM78P458APJ is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. It is equipped with a 4K*13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). With its OTP-ROM feature, the EM78P458APJ is able to offer a convenient way of developing and verifying user’s programs. Moreover, user can take advantage of EMC Writer to easily program his development code.
