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 ROM and 304 8-bit In-system programmable SRAM. Using the ICER400N, users can develop their program for ELAN's several OTP types of IC.
