1. PRODUCTS OUTLINE
1-1. Scope of Application
This specification applies to the TSC-10/IC (Lot Number: 351x * and subsequent lots).
* x = Any number
1-2. Outline
TSC-10/IC is an analog touch screen control IC that performs A/D conversion on analog signal for the
resistive analog touch screen, and transmits coordination data with 10bit resolution to the host in a
9600bps serial (asynchronous) and USB.
The serial communication enables a connection with PC’s serial port via RS-232C I/F circuit in addition to
TTL level.
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-10/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 16, where
hardware reset release enables the setting.
4-2. Communication mode setting
Communication mode setting for serial/USB is performed by setting pin number 25 to “H” or “L”. When
power supply is turned on, or hardware reset is released, pin number 25 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.

§ Connection with Host
Coordinate data, correction value or other various output data are all output to the host as a response
to IN token. Output coordinate in coordinate data mode and correction data mode is output in the
interrupt transfer, while other data is output to the host with control transfer.
4-4. Panel ID setting (USB mode)
If two touch screens to the same host are connected simultaneously, each TSC-10/IC to the host needs
panel ID setting. This function is enabled in the USB mode, by setting pin number 3 (SEL1) 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.
