Overview: AN2633 Application note
STR91xFA low power management and power consumption
Introduction
Power consumption is a significant issue for developers of embedded systems today. Whether the target application is a cellphone, MP3 player, remote control, bio-medical device or one of a whole new generation of electronic products, it is very likely that efficient power management and low current consumption are on top of the list of design goals. In terms of low power design techniques, more and more embedded designers use dynamic control of clocks and frequencies. For this reason, this application note focuses on this in the context of the STR91xFA microcontroller family. This application note is intended for system designers who require a hardware implementation overview of the STR91xFA low power modes. It includes details on the power supply circuitry and ponents, clock systems, register settings and power management.
