NXP MPC5744P-257DC Evaluation Board User Guide
A guide for the MPC5744P-257DC expansion board, used to evaluate and develop the MPC5744P automotive MCU in a 257-pin MAPBGA package.
Overview
This user guide describes the MPC5744P-257DC expansion board, a platform for evaluating and developing the NXP MPC5744P automotive microcontroller. The board supports the 257-pin MAPBGA package and can operate as a standalone unit or in conjunction with an MPC5746MMB main board. It features the MC33907 Power System Basis Chip (PwrSBC) for power management and includes JTAG, Nexus Parallel, and Nexus Aurora connectors for debugging and tracing. The document details technical configurations for jumpers, power sourcing (including external and internal regulation via NPN transistor), clocking options (40 MHz crystal, 8 MHz oscillator), and pin mappings for CAN, LIN, and SIPI interfaces.
Use Cases
- MPC5744P hardware and software development
- Microcontroller debugging and real-time tracing
- Automotive electronic control unit (ECU) prototyping
- Evaluation of MPC5744P communication interfaces
