Notes:
1. Currents are measured at 85°C junction temperature.
2. The minimum drive strength for any LVCMOS 1.2 V or 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.
3. All LVMCOS 3.3 V software macros support LVCMOS 3.3 V wide range as specified in the JESD-8B specification.
4. Applicable to V2 Devices operating at VCCI
VCC.
5. All LVCMOS 1.2 V software macros support LVCMOS 1.2 V wide range as specified in the JESD8-12 specification.
