General Description
The EM78P458 / EM78P459 are 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology. It is equipped with a 4k x 13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). With its OTP-ROM feature, it is able to offer a convenient way of developing and verifying user’s programs. Moreover, user can take advantage of the EMC Writer to easily program his development code.
