Notes:
1. Currents are measured at 85°C junction temperature.
2. Please note that 3.3 V LVCMOS wide range is applicable to 100 µA drive strength only. The configuration will NOT
operate at the equivalent software default drive strength. These values are for Normal Ranges ONLY.
3. All LVCMOS 3.3 V software macros support LVCMOS 3.3 V wide range as specified in the JESD-8B specification.
