Notes to table s:
(1) These values are specified under the recommended operating conditions shown in Table 11. See Figure 13 for more
information on switching waveforms.
(2) This minimum puls e width for pre set and clear app lies for both g lobal clear a nd array controls. The tLPA pa ra met er
must be added to this minimum width if the clear or reset signal incorporates the tLAD parameter into the signal
path.
(3) This pa r ameter is a gu id eline that is s ample -t ested o nl y and is based o n extensive device c harac t er ization. This
parameter applies for both global and array clocking.
(4) These parameters are measured with a 16-bi t load ab le, enabled , up/ d own count er pr og r ammed into ea c h LA B.
(5) The fMAX values rep re s en t th e highest fr eq uency for pipeli ned dat a.
(6) Operating conditions: VCCIO = 3.3 V ± 10% for com me rci al an d in d u stri al u se.
(7) For EPM7064S-5, E PM 7064S-6, EPM 7128S-6, EP M 7160S-6, EPM 7160S-7, EPM 7192S-7, an d EPM 7256S-7 devices,
these v alues are s pe c ified for a PIA fan-out of one LA B (16 macrocells). Fo r ea c h add itional LAB fan -out in these
devices, add an additional 0.1 ns to the PIA timing value.
(8) The tLPA parameter must be added to the tLAD, t LAC, tIC, tEN, tSEXP, tACL, and tCPPW parameters for macrocells
runn ing in the low-p ower mod e.
Tables 30 and 31 show the EPM7160S AC operating conditions.
