Thermal Characteristics
Introduction
The temperature variable in the Actel Designer software refers to the junction temperature, not the
ambient, case, or board temperatures. This is an important distinction because dynamic and static power
consumption will cause the chip's junction temperature to be higher than the ambient, case, or board
temperatures.
