Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current documentation to confirm memory capacities and temperature ratings. Confirm availability status directly with Critical Link or authorized distributors as supply conditions may vary. Ensure carrier board designs accommodate the SO-DIMM-200 connector specifications and required voltage levels for FPGA banks.

Selection Notes

Select this module when high-performance digital signal processing combined with programmable logic is required in a compact form factor. The XC6SLX45 FPGA offers significant logic resources for custom data path acceleration. Verify that the 0°C to 70°C commercial temperature range meets environmental requirements; industrial variants are available under different part numbers if wider temperature ranges are needed.
