ITEM NAME:128MB SDRAM Mister-RTC for Terasic DE10-Nano FPGA Real Time Clock Module A#S Product Description Description: 128MB SDRAM Mister-RTC Module for Terasic DE10-Nano FPGA Real Time Clock Memory Board Description: 1. This Extra Slim (XS-D) v2.5 motherboard can provide 128MB of SDR SDRAM memory for cores (including Neo Geo cores) that require a large amount of memory (> 512KB). 2. Although DE10-Nano has built-in DDR3 RAM, it has high latency and is not suitable for the timing required for retro EDO DRAM. Therefore, if a core requires precise memory timing, then onboard DDR3 cannot be used. 3. Each motherboard uses matched high-quality Alliance memory. Every 128MB SDRAM Extra Slim (XS-D) v2.5 motherboard has been tested for one hour at 140 MHz. 4. Tested using Neo Geo ROM, Acorn Archimedes (Archie) core, Game Boy Advance core, Sega Mega CD core, and Neo Geo games that require 128MB module to play, to ensure that there is no problem. Feature: Suitable for Terasic DE10-Nano FPGA Board. 128MB SDRAM capacity. Approximately 100% of the playable Neo Geo ROM. Alliance memory AS4C32M16SB-7TIN chip. MiSTer IO Board Compatible. Fully Assembled & Teste. Note: 1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! 2. Please allow 1-3mm measuring deviation due to manual measurement. Included: 1 XÂ RTC Module.Suitable for Terasic DE10-Nano FPGA Board.
