8-Bit Microprocessor with OTP ROM
1
General Description
EM78P211N and EM78P212N are 8-bit microprocessors designed and developed with low-power and high-speed CMOS technology.Each device in the series has as an on-chip 2K×13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM).Each provides a protection bit to prevent intrusion of user’s OTP memory code.Two Code option bits are.
