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 to be higher than the ambient temperature.
EQ 2-1 can be used to calculate junction temperature.
TJ = Junction Temperature = ΔT + TA
EQ 2-1
where:
TA = Ambient Temperature
ΔT = Temperature gradient between junction (silicon) and ambient ΔT = θ
ja * P
θ
ja = Junction-to-ambient of the package. θja numbers are located in Table 2-5.
P = Power dissipation
Package Thermal Characteristics
The device junction-to-case thermal resistivity is
θ
jc and the junction-to-ambient air thermal
resistivity is
θ
ja. The thermal characteristics for θja are shown for two air flow rates. The absolute
maximum junction temperature is 100°C. EQ 2-2 shows a sample calculation of the absolute
maximum power dissipation allowed for a 484-pin FBGA package at commercial temperature and
in still air.
