SGC22300_01_GF_22FDSOI is a Real Time Clock (RTC) based on the leading SGC21510 solution. Using advanced analog design techniques, to guarantee ultra-low power and ultra-low leakage, it was designed to be the brain of the Power Management Unit (PMU). Controlling the state of each regulator of the PMU, it controls if the regulators are in high, low, ultra-low or adaptive ultra-low power. Additionally, it includes anti-temper mechanisms, wake, reset or shutdown causes, that can be masked, allowing also to configure the effect of a reset. Being specified from TJ = −40°C to 125°C, it also includes ultra-low leakage configuration registers to allow the system architect to save the status bits.
