MPC5744P FlexRay Interface in Pictures
Visual guide for implementing the FlexRay communication protocol on NXP MPC5744P microcontrollers, covering timing, hardware architecture, and segment configuration.
Overview
This application note provides a detailed technical overview of the FlexRay automotive network communication protocol as implemented on the NXP MPC5744P. It explains the four-level timing hierarchy consisting of communication cycles, arbitration grids, macroticks, and microticks. The document describes the internal hardware architecture of the FlexRay module, including the Controller Host Interface (CHI), Protocol Engine (PE), and Clock Domain Crossing (CDC) unit. It further details the configuration of static segments using Time Division Multiple Access (TDMA) and dynamic segments using Flexible TDMA (FTDMA), including timing variables for bitrates ranging from 2.5 Mbit/s to 10 Mbit/s.
