4.6.2. Device Operating Temperature

The operating temperature of the FPGA is divided into the following categories:
  • Commercial grade—Used for all device families. The operating temperature range from 0 degrees C to 85 degrees C.
  • Industrial grade—Used for all device families. The operating temperature range from -40 degrees C to 100 degrees C.
  • Military grade—Used for Stratix IV device family only. The operating temperature range from -55 degrees C to 125 degrees C.
  • Automotive grade—Used for Cyclone V device families only. The operating temperature range from -40 degrees C to 125 degrees C.
