eXtreme Low-Power (XLP) PIC Microcontrollers: An Introduction to Microchip's Low-Power Devices
Brant Ivey, Rajat Hegde, Akhila Bhat
Power consumption has always been an important consideration for the design of any electrical system. This includes the embedded systems at the heart of countless modern devices and the microcontrollers that make most of these systems work- The expansion of embedded systems into markets, such as portable electronics, metering applications and medical devices, has caused power consumption to become one of the foremost concerns for embedded system designers. It is important that a microcontroller not only consume as little power as possible, but also provide features that allow for minimal power consumption in the rest of the design as well. To design the best possible system, the engineer must understand all of the power-saving features that a microcontroller might offer ? not only to make the best device selection, but how to exploit these features for the most economical power system.
This application note reviews the power-saving technology in current PIC microcontrollers, particularly nanoWatt and nanoWatt XLP Technologies. It also discusses how to select the best low-power device for a design and how to use these features to the best advantage.
