34.2 Absolute Maximum Ratings

Stresses beyond those listed in the following table, may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Table 34-1. Absolute maximum ratings
Symbol Parameter Min. Max. Units
VDD Power supply voltage 0 3.8 V
IVDD Current into a VDD pin - 28(1) mA
IGND Current out of a GND pin - 39(1) mA
VPIN Pin voltage with respect to GND and VDD GND-0.3V VDD+0.3V V
Tstorage Storage temp -60 150 °C
Note:
  1. Maximum source current is 14 mA and maximum sink current is 19.5 mA per cluster. A cluster is a group of GPIOs as shown in the following table. Each VDD/GND pair is connected to 2 clusters, hence current consumption through the pair will be a sum of the clusters source or sink currents.
