Product Description
The TSHARC C-Ray Board is a new standard in capacitive touch screen controller technology. It supports serial and
USB communication as well as all manufacturers’ capacitive touch screens regardless of whether or not the screen
includes a back shield.
The C-Ray is a high-performance touch screen controller which, in holding true to Microchip’s design fundamentals,
utilizes ‘off-the-shelf’ microcontroller technology in conjunction with Microchip’s proprietary decoding techniques and
device driver software. This virtually eliminates the threat of obsolescence while maintaining the high-performance
and utility standards expected from Microchip Technology Inc.

Integrating the TSHARC Capacitive Controller
Mounting the Controller
The controller has two .122” diameter (4-40 or 3mm screw) plated mounting holes. Notice the mounting hole closest
to the touch screen connector H4.
THIS STATIC GROUND MOUNT MUST TERMINATE TO A STATIC GROUND.
Failure to ground the controller will result in poor performance and may eliminate the effectiveness of the on board
static protection. For additional details about controller integration, please contact Microchip.
For best performance mount the controller:
1)
In such a way to keep the touch screen tail away from high EMI, RFI and power sources.
2)
“In line” with the touch screen tail limiting the number and severity of any bends or folds in the touch screen
tail.
Contact your touch screen manufacturer to determine any touch screen manufacturer’s mounting
specifications.
3)
In a way to insure that you are using a communication cable with adequate shielding which is located away
from high EMI, RFI radiating system components.
4)
To shield the controller and/or the touch screen from EMI / RFI noise in cases where required. Mounting the
controller into a metal box which is shielded might be necessary.
5)
To insure the back shielded touch screen terminates to pin #3 (center pin) of H4.
It is required if a back
shield is available.
6)
Make sure the back shield of the sensor does not come in contact with any grounded part of the system.
IF PIN #3 IS CONNECTED IN ANY WAY TO AN EXTERNAL GROUND, YOU MAY PERMANENTLY
DAMAGE YOUR CONTROLLER BOARD.
7)
Such that the board, the LCD, and the computer system all have the same ground. Failure to have the
same ground throughout the system may result in reduced controller performance.
8)
The static ground mount must be terminated to a static ground before powering on the controller board.
Failure to follow this procedure will bypass the static protection and may damage the controller causing the
board to not function properly.

Figure 2: Controller Mounting Diagram
Although Microchip Technology Inc. has taken steps to protect your touch screen controller from transient
voltage, it is important to make all grounding, communication and touch screen connections to the
controller and touch screen. This must be done before powering on your computer, video monitor or touch
screen controller. Failure to follow this procedure may result in damage to your controller and/or
communication port. If you believe that your application will require additional static protection, it is up to
you to determine the appropriate static protection needed to protect your electronics from transient voltage.
Failure to take the necessary precautions may result in damage to your controller. Microchip does
not warranty the TSHARC controller board against transient static discharge damage.
