EM78P156N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS
technology.. It is equipped with 1K*13-bits Electrical One Time Programmable Read Only Memory
(OTP-ROM). It provides three PROTECTION bits to prevent user’s code in the OTP memory from being
intruded. 8 OPTION bits are also available to meet user’s requirements.
With its OTP-ROM feature, the EM78P156N is able to offer a convenient way of developing and verifying
user’s programs. Moreover, user can take advantage of EMC Writer to easily program his development
code.
