Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings can cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions
is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time can affect device reliability.
2. Power supplies can turn on in any order.
3. For protracted periods (e.g., longer than a day), VIN should not exceed VCCO by more than 3.6 V.
4. For soldering guidelines and thermal considerations, see the "Device Packaging" infomation on www.xilinx.com.

Notes:
1. Correct operation is guaranteed with a minimum VCCINT of 2.375 V (Nominal VCCINT –5%). Below the minimum value, all delay
parameters increase by 3% for each 50-mV reduction in VCCINT below the specified range.
2. At junction temperatures above those listed as Operating Conditions, delay parameters do increase. Please refer to the TRCE report.
3. Input and output measurement threshold is ~50% of VCC.
4. Min and Max values for VCCO are I/O Standard dependant.
