TSC-30/IC Product Specification

1. 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.

4. Initial setting

4-1. EEPROM setting

Depending on that calibration is performed in either TSC-30/IC or host, you can select whether EEPROM is used or not to store the correction data. EEPROM selection can be set via pin number 50, where hardware reset release enables the setting.

(TSC-30/IC)

EEP-CS/JP9

4-2. Communication mode setting

Communication mode setting for serial/USB is performed by setting pin number 37 to “H” or “L”. When power supply is turned on, or hardware reset is released, pin number 37 is read to turn on in either USB/ serial mode.

No both communication schemes are used at a time. After the hardware reset, if setting is performed with jumper switch, the setting is enabled by power supply restart or hardware reset.

4-3. Touch screen mode setting

Touch screen mode setting for 4-wire, 5-wire or 8-wire is performed by setting pin number 60 and 61 to “H” or “L”. When power supply is turned on, or hardware reset is released, pin number 60 and 61 are read to turn on in either 4-wire, 5-wire or 8-wire mode.

4-5. Panel ID setting (USB mode)

If two (three or four) touch screens to the same host are connected simultaneously, each TSC-30/IC to the host needs panel ID setting. This function is enabled in the USB mode, by setting pin number 58 (JP4) and pin number 59 (JP5) to “H” or “L”. Setting is enabled when hardware is reset, where Device Descriptor’s iProduct is set to “0” or “1” and this value is identified by the host as panel ID.
