Notes:

1. Note that 1.2 V LVCMOS and 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.

2. Currents are measured at 125°C junction temperature.

3. All LVCMOS 3.3 V software macros support LVCMOS 3.3 V wide range as specified in the JESD-8B specification.

4. Applicable to A3PE600L and A3PE3000L 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.

6. Output drive strength is below JEDEC specification.

7. Output slew rate can be extracted using the IBIS Models.
