The Texas Instruments MSP430FR68791IPZR is a 16-bit MSP430 CPUXV2 microcontroller running at 16 MHz, with 128 KB of FRAM program memory and 2 KB of RAM. FRAM writes at bus speed and holds data without a backup battery — no EEPROM wear-leveling code needed, no Flash page-erase delays during field updates. The 16 MHz clock is enough for real-time sensor polling, LCD segment drive, and Modbus RTU frames on the UART.
