6.8 Hint 8 - Using the Power-Down Pin

The power‑down pin allows the ATF15XX device to be externally placed into a zero‑power mode. By default, the fitter disables the power‑down pin, making it available for use as a logic pin. If minimizing power consumption is a key design requirement, enabling the power‑down pin allows the device to be powered down when system conditions permit. This capability enables designers to customize power usage to meet system needs. For example, the ATF15XX can be powered down when all inputs are idle and powered back up when input activity is expected.
