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
V
5VT_PIN
and V
DD
must never exceed 3.6V.
Note 2.3 The Package Power Dissipation specification assumes a recommended thermal via design
consisting of a 3x3 matrix of 0.3mm (12mil) vias at 1.0mm pitch connected to the ground
plane with a 2.5 x 2.5mm thermal landing.
Note 2.4 Junction to Ambient (
JA
) is dependent on the design of the thermal vias. Without thermal
vias and a thermal landing, the
JA
is approximately 60°C/W including localized PCB
temperature increase.
