Energy Management Technology

In the power and energy balance, Freescale's innovators reign

Freescale is a leader in power management techniques. We recognize that power and energy are the biggest challenge facing designers and customers across a broad range of markets and applications. We are attacking power management at every level, from process and design technologies to system-level design and development software.

Everything we do is designed around power management that provides customers the greatest application possibilities.
