Notes:
1. The minimum drive strength for the default LVCMOS 1.2 V software configuration when run in wide range is ± 100 A.
The drive strength displayed in software is supported in 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 100°C junction temperature and maximum voltage.
5. Currents are measured at 85°C junction temperature.
6. Software default selection highlighted in gray.
