Notes:
1. Maximum DC undershoot below GND must be limited to either 0.5V or 10 mA, whichever is easier to achieve. During transitions, the device pins can
undershoot to –2.0V or overshoot to +7.0V, provided this over- or undershoot lasts less then 10 ns and with the forcing current being limited to
200 mA.
2. Stresses beyond those listed under Absolute Maximum Ratings might 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 adversely affects device reliability.
3. For soldering guidelines, see the information on "Packaging and Thermal Characteristics" at www.xilinx.com.

Notes:
1.
VCCINT, VCCO, and VCCJ supplies may be applied in any order.
2. At power up, the device requires the VCCINT power supply to monotonically rise to the nominal operating voltage within the specified TVCC rise time.
If the power supply cannot meet this requirement, then the device might not perform power-on-reset properly. See Figure 16, page 22.
3. If the VCCINT and VCCO supplies do not reach their respective recommended operating conditions before the OE/RESET pin is released, then the
configuration data from the PROM will not be available at the recommended threshold levels. The configuration sequence must be delayed until both
V
CCINT and VCCO have reached their recommended operating conditions.
