Section 21 Printed Circuit Board Layout Proposals
Table 21-1 Suggested External Component Values
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 capacitor connected as near as possible to the
corresponding pins(C1 - C6).
Central point of the ground star should be the VSSR pin.
Use low ohmic low inductance connections between VSS1, VSS2 and VSSR.
VSSPLL must be directly connected to VSSR.
Keep traces of VSSPLL, EXTAL and XTAL as short as possible and occupied board area for C7,
C8, C11 and Q1 as small as possible.
Do not place other signals or supplies underneath area occupied by C7, C8, C10 and Q1 and the
connection area to the MCU.
Central power input should be fed in at the VDDA/VSSA pins.
