Power
Consumption
Designers can use the Altera web Early Power Estimator to estimate the
device power.
Cyclone devices require a certain amount of power-up current to
successfully power up because of the nature of the leading-edge process
on which they are fabricated.
Table 4–17
shows the maximum power-up
current required to power up a Cyclone device.
Designers should select power supplies and regulators that can supply
this amount of current when designing with Cyclone devices. This
specification is for commercial operating conditions. Measurements were
performed with an isolated Cyclone device on the board. Decoupling
capacitors were not used in this measurement. To factor in the current for
decoupling capacitors, sum up the current for each capacitor using the
following equation:
I = C (dV/dt)
The exact amount of current that is consumed varies according to the
process, temperature, and power ramp rate. If the power supply or
regulator can supply more current than required, the Cyclone device may
consume more current than the maximum current specified in
Table 4–17
.
However, the device does not require any more current to successfully
power up than what is listed in
Table 4–17
.
The duration of the I
CCINT
power-up requirement depends on the V
CCINT
voltage supply rise time. The power-up current consumption drops when
the V
CCINT
supply reaches approximately 0.75 V. For example, if the
V
CCINT
rise time has a linear rise of 15 ms, the current consumption spike
drops by 7.5 ms.
