EM78P447S General Description
EM78P447S is an 8-bit microprocessor with low-power and high-speed CMOS technology. It is equipped with 4K*13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a PROTECTION bit 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 EM78P447S 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.
