Power Consumption

The power consumed by the XC223[04]L depends on several factors such as supply

voltage, operating frequency, active circuits, and operating temperature. The power

consumption specified here consists of two components:

•

The switching current

S depends on the device activity

•

The leakage current

LK depends on the device temperature

To determine the actual power consumption, always both components, switching current

S and leakage current ILK must be added:

DDP = IS + ILK.

Note: The power consumption values are not subject to production test. They are

verified by design/characterization.

To determine the total power consumption for dimensioning the external power

supply, also the pad driver currents must be considered.

The given power consumption parameters and their values refer to specific operating

conditions:

•

Active mode:

Regular operation, i.e. peripherals are active, code execution out of Flash.

•

Stopover mode:

Crystal oscillator and PLL stopped, Flash switched off, clock in most parts of domain

DMP_M stopped.

Note: The maximum values cover the complete specified operating range of all

manufactured devices.

The typical values refer to average devices under typical conditions, such as

nominal supply voltage, room temperature, application-oriented activity.

After a power reset, the decoupling capacitors for

DDIM are charged with the

maximum possible current.

For additional information, please refer to Section 5.2, Thermal Considerations.

Note: Operating Conditions apply.
