EM78P301N

The EM78P301N is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. The device has an on-chip 1Kx13-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 bits are also available to meet user’s requirements.
