Microchip Technology eXtreme Low Power XLP Microcontrollers

Microchip nanoWatt Technology contains extensive features which are designed to reduce overall power consumption by providing flexible, yet powerful power management solutions for your application.

• Static power is the power consumed while the application is not active (Sleep). This power dissipation comes from transistor leakage inherent in CMOS processes, real-time clocks necessary for timekeeping which run during sleep, system voltage supervisors, and watch-dog timer circuits.
• Active power is the power consumed while the application is active and executing tasks. This power dissipation is dominated by CMOS switching currents which are sensitive to execution frequency and voltage. Other power is consumed by the peripherals running on the product (like ADCs), or the state of the output pins.
• Average power is the power consumed when operating in both static and active operation states over time. The average power is affected by the amount of time spent in each state, as well as the time required to switch between sleep and active. This transfer time is referred to as fast wake-up.
