DESCRIPTION
The Zero Gecko MCUs achieve a total of 0.9 μA standby current consumption in deep-sleep mode, including active brown-out detector, power-on-reset, RTC, and RAM retention. The MCU family also provides power saving features enabling 110 μA/MHz in active mode while running real application code and 2 μs wakeup time from standby mode. The Peripheral Reflex System (PRS) allows configurable, fast and autonomous connections between the peripherals without CPU intervention, resulting in improved system performance and reduced energy consumption.TRANSCRIPT
