The power distribution from the regulator to each power plane should be made over filters (see Figure
2).
RC Filters can be inserted in the supply paths at the regulator output and at the branchings to other
module supply pins like VDDOSC, VDDOSC3, VDDFL3, VDDPF, VDDPF3, VDDM, VDDMF, VDDAF
(see Figure 2). Using inductance or ferrite beads (5 – 10 µH) instead of the resistors can improve the
EME behaviour of the circuit and reduce the radiation up to ~10dBµV on the related supply net.
OCDS must be disabled.
Select weakest possible driver strengths and slew rates for all I/Os (see Scalable Pads AppNote
AP32111).
Use lowest possible frequency for SYSCLK.
Avoid cutting the GND plane by via groups. A solid GND plane must be designed.
