RL78/G23 Group: RL78/G23 Capacitive Touch Low Power Guide (SMS function)
■This application note explains how to use the SNOOZE Mode Sequencer (SMS) to achieve low power consumption with capacitive touch measurement.
●Target Device
■RL78/G23
●When applying the contents of this application note to other MCUs, please change them according to the specifications of the MCUs and perform a thorough evaluation.
●Outline
■This application note shows the reference current when the capacitive touch measurement using the SNOOZE mode sequencer (SMS) function of the RL78/G23 is operated intermittently in 100ms cycles.
■It is possible to perform touch on/off judgment processing for capacitive touch measurement in SNOOZE mode by using the SMS function, so current consumption can be further reduced compared to “RL78/G23 Capacitive Touch Low Power Guide (SNOOZE function)”.
