Package and Reliability
The XC2000 Family devices use the package type PG-LQFP (Plastic Green - Low
Profile Quad Flat Package). The following specifications must be regarded to ensure
proper integration of the XC2785X in its target environment.
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 XC2785X is a member of the XC2000 Family of microcontrollers. It is also
compatible to a certain extent with members of similar families or subfamilies.
Each package is optimized for the device 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.
