This application report enables easy migration from MSP430F2xx Flash-based MCUs to the MSP430FR57xx family FRAM-based MCU. It covers programming, system, and peripheral considerations when migrating firmware. The purpose is to highlight differences between the two families. For more information on the usage of the MSP430FR57xx features, see the MSP430FR57xx Family User's Guide (SLAU272). Although the MSP430F2xx family is used as an example, similar considerations apply when migrating from MSP430F1xx/4xx families as well.
