Product details

64 KB FRAM — what it means for firmware strategy

64 KB of FRAM is the program store, not a separate EEPROM. Unlike Flash, FRAM tolerates byte-by-byte writes at full speed with no erase cycle, so you can treat a portion of the 64 KB as non-volatile data storage — calibration constants, last-known state, event logs — without a dedicated EEPROM chip. The 2 KB of SRAM handles stack and scratchpad.

Frequently asked questions

What is the operating voltage of MSP430FR5849?

The supply range is 1.8 V to 3.6 V, covering single-cell Li-ion and 3.3 V regulated rails.

Can MSP430FR5849IRHAR be used as a replacement for MSP430FR5848?

The MSP430FR5848 is a lower-density sibling with 48 KB FRAM versus 64 KB on this part. Pinout and peripheral set are identical in the 40-QFN package, so the FR5849IRHAR is a drop-in upgrade if the extra 16 KB is acceptable for the firmware image.
