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.

Supply current caused by

leakage

(DMP_1 powered)

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

J and the ambient temperature

A 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

DDP - 0.1 V to VDDP, all outputs (including

pins configured as outputs) disconnected. This parameter is tested at 25

°C and is valid for T

J ≥ 25 °C.

3) The pad supply voltage pins (

DDP) 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.
