Notes:
1. The minimum drive strength for any LVCMOS 1.2 V or LVCMOS 3.3 V software configuration when run in wide range is
±100 µA. Drive strength displayed in the software is supported for normal range only. For a detailed I/V curve, refer to the
IBIS models.
2. All LVCMOS 3.3 V software macros support LVCMOS 3.3 V wide range as specified in the JESD8-B specification.
3. All LVCMOS 1.2 V software macros support LVCMOS 1.2 V wide range as specified in the JESD8-12 specification.
4. Resistance is used to measure I/O propagation delays as defined in PCI specifications. See Figure 2-12 on page 2-81 for
connectivity. This resistor is not required during normal operation.
5. For specific junction temperature and voltage supply levels, refer to Table 2-6 on page 2-7 for derating values.
