If you are involved in designing battery-powered products with or without digital sensors, you probably have encountered these challenges. It is not easy to conserve battery life when the microcontroller has to frequently scan sensors and process them. Very often, you have to clock the microcontroller just at the right frequency to not consume too much power when executing algorithms or when collecting I/O data. You might also have to design for the future and be ready to operate at a higher performance if the requirements change or existing ones are enhanced. Finally, you may be new to digital sensors and is inundated with the amount of software development that must be done in order to fully utilize the benefits of sensors. The LPC54100 series of microcontrollers are designed to address all of these challenges. It is designed from the ground up to provide ultra-low power performance. It offers scalable architecture to facilitate sensor listening, sensor processing and communication without consuming a lot of power. NXP has also designed a sensor processing solution kit to provide a complete hardware (HW) and software (SW) reference to jump start the evaluation and development.
