The PCB must be carefully laid out to ensure proper operation of the voltage regulator as well as of the
MCU itself. The following rules must be observed:
Every supply pair must be decoupled by a ceramic/tantalum capacitor connected as near as possible
to the corresponding pins(C1 – C9).
Central point of the ground star should be the VSS1 pin.
Use low ohmic low inductance connections between VSS1, VSS2, VSSA, VSSX1,2 and
VSSM1,2,3.
VSSPLL must be directly connected to VSS1.
Keep traces of VSSPLL, EXTAL and XTAL as short as possible and occupied board area for C10,
C11, C14 and Q1 as small as possible.
Do not place other signals or supplies underneath area occupied by C10, C11, C14 and Q1 and the
connection area to the MCU.
Central power input should be fed in at the VDDA/VSSA pins.
