EM78P156E Description
EM78P156E is an 8-bit microprocessor with low-power and high-speed CMOS technology. There is a 1K 13bit Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides a PROTECTION bit to prevent a user’s code from intruding as well as 7 OPTION bits to match the user’s requirements.
