Abstract
A semiconductor device having a low power mode includes a buffer circuit associated with an interface pad, a power management controller (PMC), and a wakeup unit for waking up a part of the device from the low power mode. The buffer circuit is disabled in the low power mode by asserting a power on reset (POR) signal associated with the PMC. A wakeup signal is generated and provided to the wakeup unit from an analog power supply associated with the buffer circuit.
