Its program memory is 64 KB of FRAM — a non-volatile memory that writes at bus speed, consumes negligible power during write, and requires no erase cycle before reprogramming. This makes it a strong fit for data-logging, over-the-air firmware updates, and applications where every microamp matters.
Surface-mount assembly with the exposed pad soldered is assumed — without it, junction temperature rises quickly under continuous load.
The FR6972 offers 64 KB FRAM and 2K x 8 RAM; the FR6971 is a lower-density variant with 32 KB FRAM. Both share the same 64-VQFN package and peripheral set.
