Chapter 2 Electrical Specifications

Note 2.1

Stresses above those listed could cause permanent damage to the device. This is a stress

rating only and functional operation of the device at any other condition above those

indicated in the operation sections of this specification is not implied.

Note 2.2

For the 5V tolerant pins that have a pull-up resistor, the voltage difference between

V5VT_PIN and VDD must never exceed 3.6V.

Note 2.3

The Package Power Dissipation specification assumes a recommended thermal via design

consisting of a 2x2 matrix of 0.3mm (12mil) vias at 1.0mm pitch connected to the ground

plane with a 1.6 x 2.3mm thermal landing.
