20.6.1.1 Performance Levels

To help balance between performance and power consumption, the device has two performance levels. Each of the performance levels has a maximum operating frequency and a corresponding maximum consumption in µA/MHz.

It is the application's responsibility to configure the appropriate PL depending on the application activity level. When the application selects a new PL, the voltage applied on the full logic area moves from one value to another. This voltage scaling technique allows to reduce the active power consumption while decreasing the maximum frequency of the device.

PL0

Performance Level 0 (PL0) provides the maximum energy efficiency configuration.

Refer to Electrical Characteristics for details on energy consumption and maximum operating frequency.

PL2

Performance Level 2 (PL2) provides the maximum operating frequency.

Refer to Electrical Characteristics for details on energy consumption and maximum operating frequency.
