ELAN Microelectronics EM78P153S
EM78P153S is an 8-bit microprocessor with low-power and high-speed CMOS technology. It is equipped with a 1024*13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides a PROTECTION bit to prevent intrusion of user’s code in the OTP memory as well as 15 OPTION bits to match user’s requirements.GENERAL DESCRIPTION
With its OTP-ROM feature, the EM78P153S offers users a convenient way of developing and verifying their programs. Moreover, user developed code can be easily programmed with the ELAN writer. This specification is subject to change without prior notice. 3 4. 1.2004 (V1.4) EM78P153S OTP ROM 2.FEATURES
