AC test load = 30 pF for XQF32P.
Float delays are measured with 5 pF AC loads. Transition is measured at ±200 mV from steady state active levels.
Guaranteed by design, not tested.
All AC parameters are measured with V
For cascaded PROMs, if the FPGA’s dual-purpose configuration data pins are set to persist as configuration pins, the minimum
period is increased based on the CLK to CEO and CE to data propagation delays:
- T
- T
For cascaded PROMs, if the FPGA’s dual-purpose configuration data pins become general I/O pins after configuration; to allow for
the disable to propagate to the cascaded PROMs and to avoid contention on the data lines following configuration, the minimum
period is increased based on the CE to CEO and CE to data propagation delays:
