Notes to tables:
(1) These values are specified under the recommended operating conditions shown in Table 14. See Figure 13 for more
information on switching waveforms.
(2) This minimum pulse width for preset and clear applies for both global clear and array controls. The t
parameter
LPA
must be added to this minimum width if the clear or reset signal incorporates the t
parameter into the signal
LAD
path.
(3) This parameter is a guideline that is sample-tested only and is based on extensive device characterization. This
parameter applies for both global and array clocking.
(4) These parameters are measured with a 16-bit loadable, enabled, up/down counter programmed into each LAB.
(5) The f
(6) Operating conditions: V
values represent the highest frequency for pipelined data.

= 3.3 V ± 10% for commercial and industrial use.

(7) For EPM7064S-5, EPM7064S-6, EPM7128S-6, EPM7160S-6, EPM7160S-7, EPM7192S-7, and EPM7256S-7 devices,
these values are specified for a PIA fan-out of one LAB (16 macrocells). For each additional LAB fan-out in these
devices, add an additional 0.1 ns to the PIA timing value.
