This slide shows the power down modes and provides an insight into choosing the power down modes based on the application. Consider three application scenarios: The first application sleeps most of the time and requires wake up every second to process the data and then go back to sleep. These kind of applications that require fast wake up time are very likely to use sleep mode. In the second scenario, the application sleeps most of the time and wakes up every few seconds to process data and then goes back to sleep. These applications require medium wake up time and are likely to use the Low voltage sleep mode. The last application sleeps most of the time and wakes up every hour or day to process data. These applications use deep sleep mode with RTCC to get the lowest power consumption.
