5.7 ErP Power Saving Function
The two pins, ERP_CTRL0# and ERP_CTRL1#, which control the standby power rail on/off to
fulfill the purpose which decreases the power consumption when the system in the sleep state or
the soft-off state. These two pins connected to the external PMOSs and the defaults are high in the
sleep state in order to cut off all the standby power rails to save the power consumption. If the
system needs to support wake-up function, the two pins can be programmable to set which power
rail is turned on. The programmable register is powered by battery. So, the setting is kept even the
AC power is lost when the register is set. At the power saving state (FINTEK calls it G3-like state),
the F71869A consumes 5VSB power rail only to realize a low power consumption system. Below is
ErP function’s timing graphs.
