Electrical characteristics

343

SMPS is active, it feeds the VCORE on the two VDD11 pins supplied by the filtered SMPS

VLXSMPS output pin. A 2.2 µH coil and a 2.2 µF capacitor on two VDD11 pins are then

required. When LDO is active, it supplies the VCORE and regulates it using the same

capacitors on VDD11 pins. It is recommended to add a decoupling capacitor of 100 nF near

each VDD11 pin/ball, but it is not mandatory.

Caution:

Each power supply pair (such as VDD/VSS or VDDA/VSSA) must be decoupled with filtering

ceramic capacitors as shown above. These capacitors must be placed as close as possible

to, or below, the appropriate pins on the underside of the PCB to ensure the good

functionality of the device.

Current consumption measurement

The IDD parameters given in various tables in the next sections, represent the total MCU

consumption including the current supplying VDD, VDDIO2, VDDA, VDDUSB, VDDDSI, VBAT and

VDDSMPS (if the device embeds the SMPS).

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 29, Table 30 and Table 31

may cause permanent damage to the device. These are stress ratings only and the

functional operation of the device at these conditions is not implied. Exposure to maximum

rating conditions for extended periods may affect device reliability. Device mission profile

(application conditions) is compliant with JEDEC JESD47 qualification standard, extended

mission profiles are available on demand.
