Revision 10 2-1
2 – SmartFusion DC and Switching Characteristics
General Specifications
Operating Conditions
Stresses beyond the operating conditions listed in Table 2-1 may cause permanent damage to the
device.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Absolute Maximum Ratings are stress ratings only; functional operation of the device at these or any
other conditions beyond those listed under the Recommended Operating Conditions specified in
Table 2-3 on page 2-3 is not implied.

Notes:
1. For flash programming and retention maximum limits, refer to Table 2-4 on page 2-4. For recommended operating
conditions, refer to Table 2-3 on page 2-3.
2. The device should be operated within the limits specified by the datasheet. During transitions, the input signal may
undershoot or overshoot according to the limits shown in Table 2-5 on page 2-4.
