Package and Reliability
In addition to the electrical parameters, the following specifications ensure proper
integration of the XC228xM into the target system.
5.1
Packaging
These parameters specify the packaging rather than the silicon.
Note: To improve the EMC behavior, it is recommended to connect the exposed pad to
the board ground, independent of the thermal requirements.
Board layout examples are given in an application note.
Package Compatibility Considerations
The XC228xM is a member of the XC2000 Family of microcontrollers. It is also
compatible to a certain extent with members of similar series and subfamilies.
Each package is optimized for the chip it houses. Therefore, there may be slight
differences between packages of the same pin-count but for different device types. In
particular, the size of the Exposed Pad (if present) may vary.
If different device types are considered or planned for an application, it must be ensured
that the board layout fits all packages under consideration.
