GENERAL DESCRIPTION

EM78P156E is an 8-bit microprocessor with low-power and high-speed CMOS technology. There is a 1K*13-bit 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.

Because of the OTP-ROM, the EM78P156E offers users a convenient way to develop and verify their programs.

Moreover, a user’s developed code can be programmed easily by an EMC writer.
