The MSP430FR2433IRGER: The 15.5 KB program memory is FRAM, not Flash. That means writes are fast (no sector-erase delay), consume less energy per byte, and tolerate essentially unlimited cycles — a practical advantage for data-logging applications that update configuration tables frequently, or for over-the-air firmware staging where the MCU can write new code without wearing out the memory.
