Note 1:
Output timing is measured at pin threshold, with 50pF external capacitive loads (incl. test xture). Slew-rate limited output
rise/fall times are approximately two times longer than fast output rise/fall times. For the effect of capacitive loads on ground
bounce, see the “Additional XC4000 Data” section of the Programmable Logic Data Book.
Note 2:
Voltage levels of unused pads, bonded or unbonded, must be valid logic levels. Each can be congured with the internal
pull-up (default) or pull-down resistor, or congured as a driven output, or can be driven from an external source.
Note 3:
Timing is based on the XC4005E. For other devices see the XACT timing calculator.
