FLEX 6000 Programmable Logic Device Family Data Sheet
Notes:
(1) Setup times are longer when the Increase Input Delay option is turned on. The setup time values are shown with the
Increase Input Delay option turned off.
(2) Hold time is zero when the Increase Input Delay option is turned on.
Power
Consumption
The supply power (P) for FLEX 6000 devices can be calculated with the
following equations:
P= P
INT
+ P
IO
P= (I
CCSTANDBY
+ I
CCACTIVE
) × V
CC
+ P
IO
Typical I
CCSTANDBY
values are shown as I
CC0
in the “FLEX 6000 Device
DC Operating Conditions” table on pages 31 and 33 of this data sheet. The
I
CCACTIVE
value depends on the switching frequency and the application
logic. This value is based on the amount of current that each LE typically
consumes. The P
IO
value, which depends on the device output load
characteristics and switching frequency, can be calculated using the
guidelines given in Application Note 74 (Evaluating Power for Altera Devices).
The I
CCACTIVE
value can be calculated with the following equation:
I
CCACTIVE
= K × f
MAX
× N × tog
LC
×
Where:
f
MAX
= Maximum operating frequency in MHz
N = Total number of LEs used in a FLEX 6000 device
tog
LC
= Average percentage of LEs toggling at each clock
(typically 12.5%)
K = Constant, shown in Table 39
