Introduction
New low power 8-bit, 16-bit and 32-bit microcontrollers designed for portable and battery-powered handheld products include an impressive set of new features, including low power capabilities. To optimize performance and take full advantage of these MCUs, designers must understand the flexible clocking systems, resource event-driven features, and -- perhaps most important -- the way to transition to and from standby and other low power modes. Choosing the best one and taking advantage of design features based on the need of specific applications requires understanding the different low power modes that are available.
