EM78P374N数据手册Elan中文资料规格书

描述 Description

The EM78P374N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology. It has a built-in 4k x 15-bit Electrical One Time Programmable Read Only Memory (OTP-ROM) and 304 bytes In-System Programmable SRAM. Using the UIT370N, users can develop their program for applications of EM78P374N.
