TI'S MSP430 VS. OTHERS

Low Power

MSP430 does well in managing power.

Especially for remote sensing capabilities, low power draw is a major advantage.

Programming with C

16 bit microprocessor

If the computation is to be done in the hardware, 16 bit processing is much nicer than the 8 bits available in other common, low-cost MCUs

Simpler architecture:

The MSP430 uses a von Neumann architecture, which is easier to understand than the Harvard architecture used in PIC and AVR.

Flash memory:

Reprogramming the chip is easy
