Abstract
A method and circuit for waking up an I2C device are disclosed. The method includes determining whether a start signal is received; determining whether a next signal immediately received after the start signal is an address signal when the start signal is received; matching the next signal immediately received after the start signal with an address of the I2C device when the next signal is the address signal; and generating a wake-up signal to wake up the I2C device when the next signal immediately received after the start signal is matched with the address of the I2C device.
