Deep Sleep is great for applications that are inactive for long periods of time, such as remote controls, input devices, sensors and thermometers. It is also ideal for applications that need to keep accurate time while consuming minimum power because Deep Sleep supports continuous operation of the Real-Time Clock/Calendar where desired. The longer an application can stay in Deep Sleep mode, the lower the average current consumption of the device will be. Normal Sleep mode is recommended for applications that need ultrafast wake up times, complete state retention, or will only be inactive for short periods of time.
