The operating current of RL78/G22 is the lowest among RL78 Family. Furthermore, RL78/G22 has SNOOZE-mode sequencer (intelligent snooze mode). The intelligent snooze mode is an enhanced version from snooze mode in conventional RL78 and does value judging, simple computing, and controlling peripheral functions during CPU standby by SNOOZE-mode sequencer to reduce more power consumption.
