E v a lua t ing P ow e r in 5 4 S X De v ic e s
A critical element of system reliability is the ability of
electronic devices to safely dissipate the heat generated
during operation. The thermal characteristics of a circuit
depend on the device and package used, the operating
temperature, the operating current, and the systems ability
to dissipate heat.
You should complete a power evaluation early in the design
process to help identify potential heat-related problems in
the system and to prevent the system from exceeding the
device’s maximum allowed junction temperature.
The actual power dissipated by most applications is
significantly lower than the power the package can
dissipate. However, a thermal analysis should be performed
for all projects. To perform a power evaluation, follow these
steps:
Estimate the power consumption of the application.
Calculate the maximumpower allowed for the device and
package.
Compare the estimated power and maximumpower
values.
E s t im a t ing P ow e r C ons um pt ion
The total power dissipation for the 54SX family is the sum of
the DC power dissipation and the AC power dissipation. Use
Equation1 to calculate the estimated power consumption of
your application.

The power due to standby current is typically a small
component of the overall power. The Standby power is
shown below for commercial, worst case conditions (70

The DC power dissipation is defined in Equation 2 as
follows:

The power dissipation of the 54SX Family is usually
dominated by the dynamic power dissipation. Dynamic
power dissipation is a function of frequency, equivalent
capacitance and power supply voltage. The AC power
dissipation is defined as follows:
