The Spartan-XL family is tested and guaranteed between 3.0V and 3.6V
VCC. Industrial devices are tested and guaranteed at up to 100°C junction
temperature. Characterization beyond those limits has been performed and
we have found that the devices continue to operate as specified to below
2.7V and above 125°C. Xilinx is confident that all Spartan-XL devices
will continue to meet functionality and I/O level requirements to 2.7V
and 125°C, with VOH and VOL within their specifications relative to
VCC. Input thresholds, pull-up resistors, and the configuration clock
stay within their specifications.
However, the device will be up to 40% slower at these extended operating
conditions. All zero hold times remain at zero. All timing results should
be multiplied by 1.4 to generate the expected worst-case value over this
extended operating range. These values are not tested or guaranteed.
