1. Product Overview  
1-1. Products Applicable  
This specification is applicable to TSC-35/RU.  
1-2. Overview  
TSC-35/RU is 5 wire touch screen controller board that performs an A/D conversion of an analog signal of  
a 5 wire resistive touch screen, and transmits the coordinate data to the host in a 10-bit resolution serial  
correspondence at 9600bps and USB. TSC-35/RU can be used for various applications for its functions  
including the power saving mode, seven sampling speed settings (max. 150p/s *1), two external switch  
connections, and automatic calibration data loading with an external EEPROM.  
§
TSC-35/RU  
TSC-35/RU dispenses a need to newly design the peripheral circuits, and can easily  
be used by connecting to the touch screen and the host. Using the driver software *2  
enables the mouse emulation on various operation systems and dispenses the need  
to newly design the controller software.  
TSC-35/RU is the product compatible with software of the TSC-25 series.  
*1: 150 transmissions of coordinate data per second.  
*2: Please contact the local sales representatives for software availability.  
TSC-35/RU is a succeeding model of the boards of the TSC-25 series. TSC-35/RU is lead-free and com-  
pliant with RoHS.

1-3. Peripheral Composition Overview  
5 wire resistive touch screen is operated by resistance sensitive system between two layers such as film or  
glass. Two pieces of transparent materials with conductive coating are placed in the same direction as  
two electrodes face each other. The 5 wire touch screen is activated when these transparent conductive  
layers are pressed to contact each other with a finger or a pen. The one of these conductive layers func-  
tions as an X/Y-coordinates electric circuits and the other as a detection circuits.  
To measure the X-coordinates, TSC-35/RU makes two corners Vcc among four corners. And makes oth-  
ers GND. When the touch screen is pressed under this environment the voltage of the X-coordinates re-  
sistance is detected by the detection layer (A_in) at the input point (x1), where the X-Y coordinate resis-  
tance layers make contact. The detected voltage in supply side is higher than the GND side, which  
means ‘A_in’=Vcc at the point ‘E’ and ‘A_in’=0(*1) at the point ‘A’. TSC-35/RU calculates coordinates  
data starting from A/D conversion of the ‘A_in’ voltage. The Y-coordinates is measured in the same way.  
By repeating this process alternately, coordinate value at the input point is determined.  
(*1) Excluding the loss in the controller circuits and touch screen. Actual detected voltage should be  
lower than ‘Vcc - GND’ because of loss happened in the circuitry.

In USB mode, please use CN4 for connecting to host computer. When you input power supply from CN6,  
please connect also the Vbus line of the USB (CN4). Because TSC-35/RU recognizes that it was con-  
nected to the host computer with a Vbus line.
