1. GENERAL DESCRIPTION
EM78P447N is an 8-bit microprocessor with low-power and high-speed CMOS technology and
high
noise immunity.
It is equipped with 4K*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. Seven OPTION bits are also available to meet user’s requirements.
With its OTP-ROM feature, the EM78P447N is able to offer a convenient way of developing and
verifying user’s programs. Moreover, user can take advantage of ELAN Writer to easily program his
development code.
