When operating the XC223xM in a system, the total heat generated in the chip must be
dissipated to the ambient environment to prevent overheating and the resulting thermal
damage.
The maximum heat that can be dissipated depends on the package and its integration
into the target board. The “Thermal resistance
power dissipation must be limited so that the average junction temperature does not
exceed 125 °C.
The difference between junction temperature and ambient temperature is determined by
ΔT = (
The internal power consumption is defined as
P
The static external power consumption caused by the output drivers is defined as
P
The dynamic external power consumption caused by the output drivers (
on the capacitive load connected to the respective pins and their switching frequencies.
If the total power dissipation for a given system configuration exceeds the defined limit,
countermeasures must be taken to ensure proper system operation:
