Abstract: A semiconductor system capable of reducing processing time in connection processing to a USB port is provided. The semiconductor system comprises TCPM and TCPC. The TCPM and the TCPC are communicably connected via the I2C bus. The TCPM has a connection detector. The TCPC in a CC logic and a controller. The CC logic embodies a state machine. The controller controls transitions in the state machine. The controller outputs a connected state transition notification when the connected state transitions to the connected state. The connection detector receives the connected state transition notification and detects the connection of the USB port. The TCPM performs a process corresponding to the connection detection by the connection detector.

Abstract: The present invention solves a new problem that may occur when Try.SRC or Try.SNK is adopted. A controller is used to implement a DRP-compliant device that can be both power supply side and power reception side according to the USB Type-C standard. The controller is configured to be able to execute a first process of determining whether or not the Port Power Role of the opposing device is Try.SRC when the Power Role of the own device is determined to be Sink meaning the power receiver according to the sequence with the opposing device, which is the connected device, and a second process of switching the Port Power Role of the own device to SRC only and continuing the sequence with the opposing device if the Port Power Role of the opposing device is Try.SRC.
