XC5200 IOB Switching Characteristic Guidelines
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Since many internal timing parameters cannot be measured directly, they are derived from benchmark
timing patterns. The following guidelines reflect worst-case values over the recommended operating conditions. For more
detailed, more precise, and more up-to-date timing information, use the values provided by the timing calculator and used
in the simulator.

Note:
1. Timing is measured at pin threshold, with 50-pF external capacitance loads.
Slew-limited
output rise/fall times are
approximately two times longer than
fast
output rise/fall times.
2. Unused and unbonded IOBs are configured by default as inputs with internal pull-up resistors.
3. Timing is based upon the XC5215 device. For other devices, see Timing Calculator.
