voltage of the device and reapply it under a controlled condition known as sleep
mode. The device recovers into functional mode under the control of an external
PCU_WAKE signal or an internal timer.
Functional description
PCU_VDD The PCU core power. Connect to the permanent 1V0 core supply.
PCU_VDDIO The PCU must operate exclusively from the PCU_VDDIO as core volt-

on). In standard power mode PCU_WAKE should be left unconnected.
sleep state, PCU_GATE is driven low. In standard power mode PCU_GATE should
be left unconnected.
PCU_CLK should be tied to the main system clock input. If the device is to be
used in low power mode, PCU_CLK must be tied to a low power oscillator so
that the power control unit remains clocked while in sleep mode.
