Power Consumption
The amount of power that is consumed by the XC228x depends on several factors, such
as supply voltage, operating frequency, amount of active circuitry, and operating
temperature. Part of this depends on the device’s activity (switching current), part of this
is independent (leakage current). Therefore, the leakage current must be added to all
other (frequency-dependent) parameters.
For additional information, please refer to Section 5.2, Thermal Considerations.

1) The supply current caused by leakage mainly depends on the junction temperature (see Figure 12) and the
supply voltage. The temperature difference between the junction temperature TJ and the ambient temperature
TA must be taken into account. As this fraction of the supply current does not depend on the device’s activity,
it must be added to each other power consumption parameter.
2) All inputs (including pins configured as inputs) at 0 V to 0.1 V or at VDDP - 0.1 V to VDDP, all outputs (including
pins configured as outputs) disconnected. This parameter is tested at 25 °C and is valid for TJ ≥ 25 °C.
3) The pad supply voltage pins (VDDP) provide the input current for the on-chip EVVRs and the current consumed
by the pin output drivers. A small amount of current is consumed because the drivers’ input stages are
switched.
