Modular Concept
For maximum flexibility and simplicity, the EVB has been designed as a modular development
platform. The EVB main board does not contain an MCU. Instead, the MCU is fitted to an MCU
daughter card (occasionally referred to as an adapter board). This approach means that the same EVB
platform can be used for multiple packages and MCU derivatives within the MPC57xx and further
families. High density connectors provide the interface between the EVB and MCU daughter cards as
shown in the diagram below. See chapter 3.7 for more details on the daughter cards and 4.8 for more
details on the interface connectors.
