ELAN Microelectronics Corp EM78P458
the EM78P458 and EM78P459 offer users convenient ways to develop and verify their programs.GENERAL DESCRIPTION
EM78P458/EM78P459 EM78P458 and EM78P459 are 8-bit microprocessors with low-power and high-speed CMOS technology. There is a 4096*13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. Because of the OTP-ROM, Moreover, a user’s developed code can be programmed easily by an EMC writer. II.●
