Thermal characteristics
The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max × JA)
Where:
TA max is the maximum ambient temperature in °C,
JA is the package junction-to-ambient thermal resistance, in °C/W,
PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),
PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip
internal power.
PI/O max represents the maximum power dissipation on output pins where:
PI/O max = (VOL × IOL) + ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the
application.
