Subsequent Events [Abstract]
Subsequent Events [Text Block]	NOTE 19. SUBSEQUENT EVENTS On September 15, 2014, we completed the iML acquisition through a second-step merger to acquire all of the remaining outstanding shares of iML held by non-controlling interests. As of September 15, 2014, Exar owns 100% of the outstanding stock of iML. Subsequent to the end of the quarter, in October 2014 we substantively paid off $18.9 million liability for acquisition of the non-controlling interests and the $26 million business loan with CTBC. Subsequent to the end of the quarter, we finalized a significant restructuring. See “Note 11 – Restructuring Charges and Exit Costs” for additional details.
