Notes:
1. The minimum drive strength for any LVCMOS 3.3 V software configuration when run in wide range is ±100 A. Drive
strength displayed in the software is supported for normal range only. For a detailed I/V curve, refer to the IBIS models.
2. IIL is the input leakage current per I/O pin over recommended operation conditions where –0.3 V < VIN < VIL.
3. 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.
4. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.
5. Currents are measured at 85°C junction temperature.
6. Software default selection highlighted in gray.
