performance retention period is exceeded. Designers can
determine the performance retention period from the
following table.
Evaluate the percentage of time spent at the highest

Example – the ambient temperature of a system cycles
between 100°C (25% of the time) and 50°C (75% of the
time). No forced ventilation cooling system is in use. An

in
the application, is 25% at 125°C with 75% at 110°C.
Performance retention in this example is at least 16.0
years.
Note that exceeding the stated retention period may
result in a performance degradation in the FPGA below
the worst-case performance indicated in the Actel Timer.
To ensure that performance does not degrade below the
worst-case values in the Actel Timer, the FPGA must be

independent of whether or not the FPGA is operating.
The retention period of a device in storage at a given
temperature will be the same as the retention period of
a device operating at that junction temperature.
