16 MHz MSP430 CPU16 with 16 KB flash — BOM-fit for sensor and control loops
The MSP430F2252TRHAT is a 16-bit MCU from the MSP430F2xx family, built around the MSP430 CPU16 core clocked at 16 MHz. The 16 KB on-chip flash and 512 x 8 RAM provide enough headroom for moderate firmware stacks — think sensor polling, UART command parsing, and PWM motor control — without external memory. The 10-bit resolution at 1.8-3.6 V supply means each LSB is about 3.5 mV at 3.6 V — adequate for battery-voltage monitoring or thermistor readout, but not precision load-cell or strain-gauge work.
Peripheral set and connectivity — I²C, SPI, UART, LINbus
The LINbus block is useful for automotive body electronics — window lifts, mirror adjust, or seat position — where a single LIN node communicates over a 12 V power line with a master ECU. Standard MSP430 peripherals include brown-out detect (BOD), power-on reset (POR), PWM timer, and watchdog timer (WDT). The BOD ensures the core resets cleanly if the supply dips below 1.8 V — critical for battery-powered gear where the cell voltage sags under load.
