Publication number: 20080245878Abstract: Disclosed is a semiconductor device including built-in interface circuits whose operations are selected in response to initialization operation from a host apparatus coupled thereto. In the semiconductor device, a first synchronous interface circuit and a second asynchronous interface circuit using differential signals, share the external terminals of the differential signals (the external differential signal terminals). For example, the semiconductor device adopts an MMC interface circuit as the first interface circuit and a USB interface circuit as the second interface circuit, while keeping the IC card interface function. The semiconductor device selects operations of the adopted interface circuits exclusively. One selection method is to enable an interface operation of the first interface circuit, upon detection of a plurality of edge changes in a clock input from an external clock terminal, which is for initializing the first interface circuit when power supply to the semiconductor device is started.Type: ApplicationFiled: March 18, 2008Publication date: October 9, 2008Inventors: Shigemasa SHIOTA, Shigeo Kurakata, Shinsuke Asari, Tetsuya Iida, Shinichi Fukasawa
