Google image search returns birds and balls with this image but, as far as I see, it has nothing to do with them.

I bought the board from Chinese site "www.21eda.com" but it is now closed. I have tried to find information in Chinese, more here, but I am unable to spot the right specs, I had them so I have some sense what they look like. How can I find schemantics (showing the logic/IOs/etc in the board)?


  1. Cyclone II EP2C5T144C8N K BBD9Y0931A

  2. Some chip: AM29LV160DB - 90EF 0929FBA D 1998 AMD

  3. Some chip: Hynix 002F A HY57V641620FTP-6 KOR

  4. Board ID: SN:21EDA0811577 (at the back of the board like here)

  5. Probably the board here, now have to find the schematics/getting-started material.

  • \$\begingroup\$ AM29LV160DB = AMD 16 Megabit (2M x 8-Bit/1M x 16-Bit) CMOS 3.0 Volt-only Boot Sector Flash Memory ... HY57V641620F = Hynix 64Mb Synchronous DRAM based on 1M x 4Bank x16 I/O \$\endgroup\$ – Adam Lawrence Jan 13 '12 at 17:21

It looks like it's this one: http://www.aliexpress.com/store/801899/210558845-449776833/Free-shipping-FPGA-21EDA-EP2C5T144-development-board-FPGA-learning-board-NIOS-dev-board.html

I'm guessing it's an evaluation board for an Altera CycloneII FPGA with Nios II Processor.

  • \$\begingroup\$ You probably mean the Altera Cyclone II with a NIOS soft core (check the FPGA label). \$\endgroup\$ – W5VO Jan 13 '12 at 17:55
  • \$\begingroup\$ Ah yes - the product description says CycloneII \$\endgroup\$ – Paul R Jan 13 '12 at 18:31
