MAX 7000 Programmable Logic Device Family Data Sheet
Notes to tables:
(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 pulse width for preset and clear applies for both global clear and array controls. The
t
LPA
parameter
must be added to this minimum width if the clear or reset signal incorporates the
t
LAD
parameter into the signal
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
MAX
values represent the highest frequency for pipelined data.
(6)
Operating conditions: V
= 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.
(8)
The
t
LPA
parameter must be added to the
t
LAD
, t
LAC
, t
IC
, t
EN
,
t
SEXP
,
t
ACL
, and
t
CPPW
parameters for macrocells
running in the low-power mode.
Tables 26
and
27
show the EPM7064S AC operating conditions.
