Kinetis KL26 Sub-Family, Rev2 08/2014. Terminology and guidelines 8.3 Definition: Attribute An attribute is a specified value or range of values for a technical characteristic that are guaranteed, regardless of whether you meet the operating requirements. 8.3.1 Example This is an example of an attribute: Symbol CIN_D Description Input capacitance: digital pins Min. — Max. 7 Unit pF 8.4 Definition: Rating A rating is a minimum or maximum value of a technical characteristic that, if exceeded, may cause permanent chip failure: • Operating ratings apply during operation of the chip. • Handling ratings apply when the chip is not powered. 8.4.1 Example This is an example of an operating rating: Symbol VDD Description 1.0 V core supply voltage Kinetis KL26 Sub-Family, Rev2 08/2014.
