Notes:

9. ILOAD includes the pull-up resistor current via terminal VPU

10. The minimum voltage in Suspend mode is 2.7V.

11. Not tested in production, value based on characterization.

12. Excludes any current from load and VPU current to the 1.5kΩ resistor.

13. Includes current between Vpu and the 1.5k internal pull-up resistor.

14. When VCCIO < 2.7V, minimum value for VREGTH = 2.0V for supply present condition.

15. DC electrical measurements should be taken with unused inputs and I/O pins connected to a valid logic level. This applies for all

modes of device operation defined in the Functional Tables on Page 4.
