The XEM6110 has been discontinued.
The Opal Kelly XEM6110 is a new integration module based on a Xilinx Spartan-6 (XC6SLX45) FPGA. In addition to a high gate-count FPGA, the XEM6110 utilizes the blazing transfer rate of PCI Express for configuration downloads, enabling an almost instant reprogramming of the FPGA, without shutting down the computer.
