FRAM-based MSP430 — what sets this MCU apart
Its program memory is 15.5 KB of FRAM — a non-volatile memory that combines the write speed and endurance of SRAM with the retention of Flash, eliminating the need for separate EEPROM and simplifying field-update firmware strategies.
The 16 MHz clock rate on a 16-bit RISC core is enough for sensor polling, PID loops, and communication protocol handling in most embedded control applications. If you are coming from an MSP430F series part, the CPU16 core is instruction-set compatible, so existing assembly or C code ports with minimal changes.
Supply rail and temperature — design-in notes
The 56-TSSOP package (6.10 mm body width) is a common footprint; verify your PCB land pattern matches the supplier package drawing before committing the board.
