Suited for such power-sensitive and critical applications as smoke, CO, motion, lighting control, and GFCI solutions, RL78/I1D Series integrates analog peripherals, hardware safety features, and flexible clocking sources. Power management options include 57 μA/MHz operation, 0.64 mA (RTC + LVD) halt, 220 nA (RAM retained) stop, and 700 μA (UART) or 500 μA (ADC mode) snooze. Along with 4 μsec wake up from STOP mode, MCUs offer multiple on-board clock sources.
