Electrical characteristics

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

4.6.1 I/O pad types

The device provides four main I/O pad types depending on the associated alternate functions:

• Slow pads—are the most common pads, providing a good compromise between transition time and low

electromagnetic emission.

• Medium pads—provide transition fast enough for the serial communication channels with controlled current to reduce

electromagnetic emission.

• Fast pads—provide maximum speed. These are used for improved Nexus debugging capability.

• Input only pads—are associated with ADC channels and 32 kHz low power 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.
