Abstract
A technique capable of normally transmitting a LPM token from a transceiver to a USB device is provided. A semiconductor device includes: a controller including a first interface circuit in conformity with UTMI+ standards; a converting circuit including a second interface circuit in conformity with the UTMI+ standards and a third interface circuit in conformity with ULPI standards, the second interface circuit converting data transmitted from the first interface circuit and received, and the third interface circuit transmitting the converted data; a first circuit analyzing a packet output from the controller and identifying and holding a packet identifier contained in the packet; and a second circuit providing a transmission command, after which a data string containing the packet identifier indicating LPM bringing a USB device to a low power consumption state is added, if the first circuit determines that the packet identifier is the LPM.
