6 Conclusion

The hardware I2C peripheral and its built-in features help the MSP430 MCU to easily adopt SMBus protocols. The ultra low-power operation of the MSP430 MCU is useful when interfacing with power management devices such as the smart battery systems used in notebook computers, cameras, cellular phones, or other portable electronic devices on a SMBus network.
