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
standard are given in Table 2-18 on page 2-18.
4. The programming temperature range supported is T
ambient
= 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
corresponding VCCI pins. See the "VMVx I/O Supply Voltage (quiet)" section on page 3-1 for further information.
7. 3.3 V wide range is compliant to the JESD8-B specification and supports 3.0 V VCCI operation.

Notes:
1. This is a stress rating only; functional operation at any condition other than those indicated is not implied.
2. These limits apply for program/data retention only. Refer to Table 2-1 on page 2-1 and Table 2-2 for device operating
conditions and absolute limits.
