1.4 Power-Down Control

The ATF15XX devices support a pin-controlled power-down option which, when enabled, allows the user to place the device into a Zero-Power mode with standby current in the microampere range. In addition, the ATF15XXASL/ASVL low-power devices include an automatic power-down feature that powers down the device when no transitions occur on any inputs, internal feedbacks or I/O pins. The ATF15XX fitter provides a command option to enable the pin-controlled power-down feature.
