STANDARD Micro Controller Specification NC41120-0021 Serial/USB Interface Controller Chip For 5-Wire Resistive Touch Panels n FEATURES • The control IC and the Fujitsu 5-wire touch panel converts pen or finger pressure on a specific location into coordinate axis values and outputs them as serial data. • RoHS compliant n FUNCTION OVERVIEW • The control IC and the Fujitsu 5-wire touch panel converts pen or finger pressure on a specific location into coordinate axis values and outputs them as serial data. • Interface can be selected from USB or Serial • This control IC can be operated by the USB host controller as a standard HID device. • Mouse-mode or digitizer-mode can be selected by terminal setting of PID4, PID3, PID2, PID1. • If mouse-mode is selected, the control IC transmits 3 button (left, middle, right button) status and the absolute coordinates to the USB host. • If digitizer-mode is selected, the control IC can be operated as digitizer of HID. • If serial is chosen the control IC can be switched to PNP or non-PNP with the I/F SEL terminal. • In addition, the control IC can be selected in coordinates-mode, standard 12bit or expanded 14bit with the MODE SEL terminal.
