The PAC board has :
8GB Double Data Rate 4 (DDR-4) Memory Banks with error correction code (ECC)
(2 banks) operating at 2133 Mbps. There are two banks, each of 4 GB capacity.
• The memory width is 64 data bits plus 8 ECC bits
• 1 Gb (128 MB) Flash – for use with the FIM
You have to use the Intel PAC , FIM and related software to develop for this board. You may not be able to use this board as a standalone FPGA development kit. It is only meant for PAC functions.
