Notes:
1. All parameters representing voltages are measured with respect to GND unless otherwise specified.
2. To ensure targeted reliability standards are met across ambient and junction operating temperatures, Microsemi
recommends that the user follow best design practices using Microsemi’s timing and power simulation tools.
3. The ranges given here are for power supplies only. The recommended input voltage ranges specific to each I/O
4. The programming temperature range supported is Tambient = 0°C to 85°C.
5. VPUMP can be left floating during operation (not programming mode).
6. VMV and VCCI should be at the same voltage within a given I/O bank. VMV pins must be connected to the
7. 3.3 V wide range is compliant to the JESD8-B specification and supports 3.0 V VCCI operation.
