During a period of system inactivity the MachXO "C" (VCC= 1.8/2.5/3.3V) PLDs can be placed in sleep mode. A SLEEPN pin controls the mode of the device. During sleep mode the standby current is reduced by over 100X. Power supplies do not have to be switched, they are in their operating range.

In under 100ns after SLEEPN input is pulled low the device enters into sleep mode. The device wakes up within 1ms after the SLEEPN input is pulled high.
