Notes:

1. IIL is the input leakage current per I/O pin over recommended operation conditions where –0.3 V < VIN < VIL.

2. IIH is the input leakage current per I/O pin over recommended operating conditions VIH < VIN < VCCI. Input current is

larger when operating outside recommended ranges

3. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.

4. Currents are measured at 85°C junction temperature.

5. Software default selection highlighted in gray.
