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

T
ΔT = Temperature gradient between junction (silicon) and ambient ΔT = θ
θ
P = Power dissipation
Package Thermal Characteristics
The device junction-to-case thermal resistivity is θ
resistivity is θ
operating junction temperature is 100°C.
operating power dissipation allowed for a 484-pin FBGA package at commercial temperature and
in still air.
