Legacy FPGAs are devices that we no longer recommend for new designs. Some of these devices may have corresponding End-of-Life (EOL) notifications, indicating that we intend to cease shipment of these products in the near future. Other legacy devices listed may still be in full production, but there may be alternative pin-compatible and functionally equivalent FPGAs available that use a more recent manufacturing process.
You can migrate our legacy FPGA devices to newer devices to for better performance, higher density, lower power consumption and better reliability.
Notes:
* C = Commercial, I = Industrial, A = Automotive, M = Military, B = MIL-STD-883 Class B
