Product Descriptions

The EM78P374N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology.  It is used for 15 bits kernel simulation and it simulates the 4K15-bit programmable ROMand 3048-bit In-system programmable SRAM.Using the ICE370N, users can develop their program for ELAN’s several OTP types of IC.
