Notice: Nallatech’s PCIe compliant FPGA boards rely on the host’s cooling capabilities to stay within its acceptable operating temperature limits.

The user must make sure that the FPGA application is designed within the power limits documented by Nallatech and that sufficient cooling is provided to make sure the maximum FPGA die temperature is 15C below the maximum operating limit. Nallatech recommends that users perform a thermal characterization of their application in their system to meet these requirements.

» Cooling: Air convection
» Operating temperature: 5°C to 35°C

» 520C FPGA card
» USB cable (front panel access)
» Built-In-Self-Test (BIST)
» OpenCL “HPC” Board Support Package (BSP)*
» 1 year access to online support lounge
