Thermal Characteristics
Introduction
The temperature variable in 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 1 can be used to calculate junction temperature.
TJ = Junction Temperature = T + TA
EQ 1
where:
TA = Ambient Temperature
T = Temperature gradient between junction (silicon) and ambient T = ja * P
ja = Junction-to-ambient of the package. ja numbers are located in Table 2-5.
P = Power dissipation
Package Thermal Characteristics
The device junction-to-case thermal resistivity is
jc and the junction-to-ambient air thermal resistivity is
ja. The thermal characteristics for ja are shown for two air flow rates. The absolute maximum junction
temperature is 110°C. EQ 2 shows a sample calculation of the absolute maximum power dissipation
allowed for an 896-pin FBGA package at commercial temperature and in still air.
