MAX 9000 Programmable Logic Device Family Data Sheet
The parameters in this equation are shown below:
MC
TON
= Number of macrocells with the Turbo Bit option turned on,
as reported in the MAX+PLUS II Report File (
.rpt
)
MC
DEV
= Number of macrocells in the device
MC
USED
= Number of macrocells used in the design, as reported in the
MAX+PLUS II Report File
f
MAX
= Highest clock frequency to the device
tog
LC
= Average percentage of logic cells toggling at each clock
(typically 12.5
%
)
A, B, C = Constants, shown in
Table 22
This calculation provides an I
CC
estimate based on typical conditions with
no output load, using a typical pattern of a 16-bit, loadable, enabled
up/down counter in each LAB. Actual I
CC
values should be verified
during operation, because the measurement is sensitive to the actual
pattern in the device and the environmental operating conditions.
Figure 15
shows typical supply current versus frequency for MAX 9000
devices.
