Notes:
1. All parameters representing voltages are measured with respect to GND unless otherwise specified.
2. The programming temperature range supported is Tambient = 0°C to 85°C.
3. VPUMP can be left floating during normal operation (not programming mode).
4. The ranges given here are for power supplies only. The recommended input voltage ranges specific to each I/O
5. 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.
6. 3.3 V wide range is compliant to the JESD8-B specification and supports 3.0 V VCCI operation.
