Abstract

This migration guide describes the hardware and software differences to consider when moving between F2838x and F28P65x C2000™ MCUs. This document shows the block diagram between the two MCUs as a visual representation on what blocks are similar or different. It also highlights the features that are unique between the two devices for all available packages in a device comparison table. To facilitate application and hardware migration between F2838x and F28P65x devices, the PCB hardware section provides guidance on how to proceed with the common 176-pin package. The digital general-purpose input/output (GPIO) and analog multiplex comparison tables show pin functionality between the two MCUs. This serves as a reference for hardware design and signal routing when considering a move between the two devices.
