With 33 I/O lines and a 14-channel 12-bit ADC, this part can handle a multi-sensor front end — think temperature, pressure, and current sense on a single chip.
For a BOM line, that means no near-term supply risk and no forced redesign.
Within the MSP430FR584x family, the MSP430FR5849 adds more FRAM and RAM but shares the same 40-VQFN (6x6) footprint and peripheral set. For a direct drop-in, compare the FRAM and RAM sizes against your firmware budget — the 48 KB FRAM and 2 KB RAM of the 5848 cover most sensor-logging and control applications without overspending.
The MSP430FR5848IRHAT is programmed via the standard MSP430 JTAG or Spy-Bi-Wire (SBW) interface, supported by TI's Code Composer Studio and IAR Embedded Workbench. The FRAM memory can be written at run time without an erase cycle, which simplifies firmware update routines.
