The use of battery-operated electronics gadgets is increasing fast in our daily lives. Products are expected to be versatile, while consuming minimal power. Redt,lced power consumption has added advan¬tages of smaller sIze and cost-effective products.

The MSP430 family of ultra-Iow¬power microcontrollers from Texas Instruments meets these requirements well. These microcontrollers combine a number of precision components like comparators and analogue-to-digital converters with the versatility of a 16¬bit CPU, Flash memory and many digital modules. The entire architecture is aimed at operating the end prq,duct at the lowest power without compromising on accuracy and functionality.
