2.1.1. Agilex™ 5 FPGA Temperature Rating

Agilex™ 5 FPGAs are designed and rated to operate at 100⁰ C junction temperature for 11.4 years.

The timing analysis of any design in the Quartus® Prime software is performed for 100⁰ C by default. Some operations may require operating at temperatures above 100⁰ C; for such conditions, refer to:

AN 950: Temperature Excursions for Stratix® 10 and Agilex™ 7 F-Series/I-Series Device Families

(Although the above document does not target Agilex™ 5 devices specifically, the basic principles are applicable.)

Short term operation of the FPGA at temperatures above 100⁰ C may not impact the device's total life span; however, you must ensure there is sufficient cooling to stabilize the FPGA temperature at a higher temperature, but below 110⁰ C, otherwise the FPGA may enter thermal runaway and eventually cease operation.
