In consideration of need to filter the MCU pins as well near the GND area bridge consider a layout like shown below.
In this make the GND areas bridge just as wide as you need and no more. You should consider the possibility to let this extend a small amount under the package of MCU. Then make matching VDD planes with same plane splits as GND planes but have NO bridge to it. Use the path through the power ferrite bead to connect the DVDD plane to the AVDD plane. Michael Karas |
