PINT is the product of IDD and VDD, expressed in watts. This is the chip internal power.
PI/O represents the power dissipation on input and output pins; user determined.
Most of the time for the applications, PI/O< PINT and may be neglected. On the other hand, PI/O may be significant, if the device
is configured to continuously drive external modules and/or memories.
An approximate relationship between PD and TJ (if PI/O is neglected) is given by:
PD = K / (TJ + 273 °C)
Eqn. 2
Therefore, solving equations 1 and 2:
K = PD x (TA + 273 °C) + RθJA x PD
2
Eqn. 3
Where:
K is a constant for the particular part, which may be determined from Equation 3 by measuring PD (at equilibrium)
for a known TA. Using this value of K, the values of PD and TJ may be obtained by solving equations 1 and 2
iteratively for any value of TA.

I/O pad electrical characteristics
4.7.1
I/O pad types
The device provides four main I/O pad types depending on the associated alternate functions:
Slow pads—These pads are the most common pads, providing a good compromise between transition time and low
electromagnetic emission.
Medium pads—These pads provide transition fast enough for the serial communication channels with controlled
current to reduce electromagnetic emission.
Fast pads—These pads provide maximum speed. There are used for improved Nexus debugging capability.
Input only pads—These pads are associated to ADC channels and 32 kHz slow external crystal oscillator providing
low input leakage.
Medium and Fast pads can use slow configuration to reduce electromagnetic emission, at the cost of reducing AC performance.
