Electrical Characteristics; Absolute Maximum Ratings - Infineon Cypress WICED CYW43903 Manual

13. Electrical Characteristics

Note: Values in this data sheet are design goals and are subject to change based on the results of device characterization.

13.1 Absolute Maximum Ratings

Caution! The absolute maximum ratings in
limits are exceeded for only a brief duration. Functional operation is not guaranteed under these conditions. Operation at absolute
maximum conditions for extended periods can adversely affect long-term reliability of the device.
