Products outline 1-1. Scope of Application This specification applies to the TSC-30/IC. 1-2. Outline TSC-30/IC is an analog touch screen control IC that performs A/D conversion on analog signal for the 4-wire, 5-wire and 8-wire resistive analog touch screen, and transmits coordination data with 10bit resolution to the host in a 9600bps serial (asynchronous) and USB. At the coordinate detection, internal filtering process provides a stabilized coordinate value. By using the correction function, in addition to the losses that occur in the circuit, display deflection between touch screen input point that occur in each element and indicator cursor can be corrected to adjust the display position. 1-3. Features § Two coordinate output modes are provided and selected per application: “Coordinate data mode” where coordinate information is sent with 10bit resolution as it is, and “correction data mode” where read coordinate is converted to the indicator’s display coordinate and sent. § “Correction data mode“ is available after EEPROM is externally attached. It enables to set up to nine correction points. Coordinate data can be corrected with the base of correction points. Using this function allows the host driver to make the implementation of correction function unnecessary. In addition, by placing correction points at the touch screen center and center points of four edges of touch screen, resistance value deviation of transparent electrode film can be corrected. § USB has multi-touch screen function enable two simultaneous connections to the host. § Two external switch functions are always available in the coordinate (correction) data mode. Two pieces of external switch information are, at the transmission of coordinate data, included in the coordinate data as pen-down/pen-up information. Since in the pen-up mode, pen-up data can be always output to the host, this switch is available as a function switch. § At the touch screen input, buzzer and LED outputs are available. Input confirmation via display and sound is available. § In the serial communication, when no touch screen input is performed, the state moves to “power-save mode“ so that such application can be supported that requests a low power consumption. In USB mode, USB suspend is supported and restored by the external interrupt of touch screen input. § Seven types of coordinate output rates are provided and either can be selected per application among seven types: six types from 30 to 150p/s plus one type, a point mode that outputs the coordinate only one time when pen-down is performed. 1-4.
