FLEX 10KE Embedded Programmable Logic Devices Data Sheet
Power
Consumption
The supply power (P) for FLEX 10KE devices can be calculated with the
following equation:
P = PINT + PIO = (ICCSTANDBY + ICCACTIVE) × VCC + PIO
The ICCACTIVE value depends on the switching frequency and the
application logic. This value is calculated based on the amount of current
that each LE typically consumes. The PIO value, which depends on the
device output load characteristics and switching frequency, can be
calculated using the guidelines given in Application Note 74 (Evaluating
Compared to the rest of the device, the embedded array consumes a
negligible amount of power. Therefore, the embedded array can be
ignored when calculating supply current.
The ICCACTIVE value can be calculated with the following equation:
ICCACTIVE = K × fMAX × N × togLC ×
Where:
fMAX
=
Maximum operating frequency in MHz
N
=
Total number of LEs used in the device
togLC
=
Average percent of LEs toggling at each clock
(typically 12.5%)
K=
Constant
Table 80 provides the constant (K) values for FLEX 10KE devices.
This calculation provides an ICC estimate based on typical conditions with
no output load. The actual ICC should be verified during operation
because this measurement is sensitive to the actual pattern in the device
and the environmental operating conditions.
