Migrating from MPC5643L to MPC5744P

2021-08-19
Introduction:
●The MPC5643L 32-bit MCU built on Freescale's Power Architecture® technology is the first MCU to achieve ISO 26262 ASIL D functional safety standard certification. It targets chassis and safety applications that require a high safety integrity level, such as electric power steering, radar and electronic stability control. The MPC5744P MCU is the 55 nm successor to the MPC5643L. The MPC5744P is built around a safety concept targeting an ISO 26262 ASIL D integrity level and is part of the SafeAssure program. Its peripheral set is compatible with the MPC5643L to allow a high degree of reuse.
●This application note provides a summary of the significant differences between the MPC5643L and MPC5744P devices, and may be used as a reference for planning a migration to the MPC5744P. This document covers the architectural differences between the two devices and highlights the software and hardware considerations for migrating an existing MPC5643L-based design to the MPC5744P.
