Power-Up I
CC
Power-up I
CC
is and estimation of the current required to successfully
power-up the device and is observed on the V
CCINT
power supply. For
Stratix and Stratix GX devices, the PowerPlay early power estimator
provides both the typical and maximum power-up I
CC
. For Cyclone
devices, the PowerPlay early power estimator provides the maximum
power-up I
CC
.
The power-up I
CC
current is not added to the total current (I
CCINT
) because
it is only observed when the device is powering up. The power-up
current is independent of the current consumption during device
user-mode. If the power-up I
CC
is greater than the total I
CCINT
, you should
select a regulator that supports the maximum power-up I
CC
requirement.

CC
, refer to the DC & Switching
Characteristics chapter of the appropriate device family handbook.
Total
The Total section displays the total current and power estimation for the
internal logic array (Internal V
CCINT
), the I/O interface (I/O (V
CCIO
)), the
transceiver (Transceiver (V
CC
)), if applicable, and the total power
consumption for the whole design. The total I
CCINT
and P
INT
are the
summation of all the subtotals of the I
CCINT
and P
INT
calculated in each
section. The total I
CCIO
and P
IO
are the summation of all the subtotals of
the I
CCIO
and P
IO
calculated in the relevant sections. For the Stratix GX
PowerPlay early power estimator, the total power consumed by the
high-speed transceiver blocks is listed separately as P
TRANSCEIVER
. The
