48.1 Absolute Maximum Electrical Characteristics

Absolute maximum ratings are listed below. Exposure to these maximum rating conditions for extended periods may affect device reliability. Functional operation of the device at these or any other conditions, above the parameters indicated in the operation listings of this specification, is not implied.

Note:
  1. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions, above those indicated in the operation listings of this specification, is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
  2. Maximum allowable current is a function of device maximum power dissipation.
  3. See the Pinout for the 5V tolerant pins.
  4. When applying higher or lower voltage than those specified on I/O pins, refer to DI_19 or DI_21 to respect the maximum injection current specification.
  5. A cluster is a group of GPIO’s bounded by power/ground pins. Refer to the following table I/O Clusters.
  6. This maximum value is specific to continuous DC current. For I/O pin AC current characteristics, refer to the I/O Pin Electrical Specifications.
