Patent number: 10580345Abstract: Provided is a display driver which can be used in common in any of COF mounting and COG mounting. In the display driver, a position (or write/output position) of display data output by an output circuit can be changed along a direction of an array of external output terminals S1 to S540 according to mode data, whereby an array of external output terminals to use for output can be selected from more than one kind of arrays different in layout pitch. Therefore, the display driver can be used in display panels with signals lines having different pitches serving to receive drive signals from the display driver and in addition, used in common in any of COF mounting and COG mounting which are different from each other in the pitch of mounting wiring lines.Type: GrantFiled: May 29, 2019Date of Patent: March 3, 2020Assignee: Synaptics Japan GKInventors: Goro Sakamaki, Kei Miyazawa

Patent number: 10043491Abstract: The present invention is to provide a semiconductor device that can correctly switch endians on the outside even if the endian of a parallel interface is not recognized on the outside. The semiconductor device includes a switching circuit and a first register. The switching circuit switches between whether a parallel interface with the outside is to be used as a big endian or a little endian. A first register holds control data of the switching circuit. The switching circuit regards the parallel interface as the little endian when first predetermined control information, that is unchanged in the values of specific bit positions even if its high-order and low-order bit positions are transposed, is supplied to the first register, and regards the parallel interface as the big endian when second predetermined control information, that is unchanged in the values of specific bit positions even if its high-order and low-order bit positions are transposed, is supplied to the first register.Type: GrantFiled: August 15, 2017Date of Patent: August 7, 2018Assignee: Renesas Electronics CorporationInventors: Goro Sakamaki, Yuri Azuma
