METHOD AND DEVICE FOR LOW POWER CONTROL

摘要

The present application discloses an integrated circuit having a power controller that can manage power modes of a system when the system is in a low power mode. According to an embodiment, a power controller is built into an input/output (I/O) region of and integrated circuit die, wherein the I/O region is outside the main logic area of the die. The same supply voltage that powers the I/O region of the device can power the power controller. The power controller can operate to transition the integrated circuit die between power modes by transitioning logic modules of the integrated circuit between power states without intervention by the logic modules.
