3.3.1 Example
This is an example of an attribute:
Symbol Description Min. Max. Unit
CIN_D Input capacitance:
digital pins
— 7 pF
3.4 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.
