EM78P447S 8-Bit Microprocessor

EM78P447S is an 8-bit microprocessor with low-power and high-speed CMOS technology. There is a 4096*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 8 other OPTION bits to match the user’s requirements. Because of the OTP-ROM, the EM78P447S offers user.
