GENERAL DESCRIPTION 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. This specification is subject to change without prior notice. 3 07.29.2004 (V1.2) EM78P156N OTP ROM 2.
