This eliminates the need for wear-leveling algorithms in data-logging or configuration-storage tasks, and it keeps the firmware update path simple: write new code directly over FRAM without sector-erase delays. The device also carries 1K x 8 of RAM for stack and scratchpad data.
The MSP430FR59671IRGZT is a higher-density sibling in the same FRAM family, typically offering more program memory and RAM. The MSP430FR58671IRGZT provides 32 KB FRAM and 1K x 8 RAM, while the FR59671 variant steps up to a larger memory array. Both share the same CPUXV2 core, 16 MHz speed, 48-VQFN package, and peripheral set, so a board designed for one can often accommodate the other with a firmware memory-map change.
Yes, the MSP430FR58671IRGZT uses the standard Spy-Bi-Wire (SBW) or JTAG debug interface common to all MSP430 devices. The MSP430-FET programmer/debugger supports this part through the 4-pin SBW connection, which only requires VCC, GND, SBWTDIO, and SBWTCK signals.
