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 parameter applies to MAX 7000E devices only.
(3)
This minimum pulse width for preset and clear applies for both global clear and array controls. The
t
parameter
must be added to this minimum width if the clear or reset signal incorporates the
t
LAD
parameter into the signal
path.
(4)
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.
(5)
These parameters are measured with a 16-bit loadable, enabled, up/ down counter programmed into each LAB.
(6)
The
f
values represent the highest frequency for pipelined data.
(7)
Operating conditions: V
= 3.3 V
±
10
%
for commercial and industrial use.
(8)
The
t
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 24
and
25
show the EPM7032S AC operating conditions.
