Why Is Ultra-Low Power Important?

• Longer battery life

• Lower cost batteries

• Portable applications

• Permanent batteries

reduce liability

• Reduced EMI simplifies PCB

• Simpler power supplies

Is ultra-low power really important in all applications?

•The most apparent benefit for low-power is realized in battery powered applications. Reduced

power consumption allows the use of smaller lower cost batteries.

•Another benefit in battery powered application is the concept of permanently installed batteries.

The idea is to install sealed batteries at the factory that are not replaceable. With permanently

sealed batteries in an application such as a portable medical device, replacement liability is

eliminated. Cost is also reduced. With MSP430’s ability to operate <1uA, it is very possible to

develop product the operate from a single lithium battery for over 10-years.

•Generated EMI is very low because the MSP430 is so low power and can operate effectively at

low-frequencies,.

•Even in application that have a power supply, low-power is an advantage. Smaller, lower cost

power supplies can be used.
