The 16 MHz clock rate on the 16-bit RISC core. The internal oscillator eliminates the external crystal.
On-chip peripherals include brown-out detect, POR, DMA, PWM, and a watchdog timer. The 8-channel 10-bit ADC handles analog sensor inputs.
The supply voltage range is 1.8 V to 3.6 V, covering single-cell Li-ion, two-cell alkaline, or a regulated 3.3 V rail.
The MSP430G2131 is a potential pin-compatible replacement in the same package, but it has half the Flash memory (512 bytes vs 1 KB). Verify your firmware fits before substituting.
