The MSP430FR5735IDA: FRAM writes at bus speed, consumes microamps in standby, and retains data without a backup battery. The 24 MHz core clock is enough for sensor fusion, simple control loops, and protocol handling over the I²C, SPI, or UART interfaces.
The 1K x 8 RAM is tight — it forces careful allocation for buffers and stacks, but the FRAM can double as data storage if you treat it as unified memory.
The F280041PZQR is a 32-bit C28x Piccolo MCU with 100 MHz, Flash memory, and 125°C rating, but it is a different architecture, speed grade, and temperature range — not a pin-compatible or software-compatible second source. For a true FRAM-based MSP430 alternative, look at other MSP430FR5xxx family members with similar peripheral sets.
