The schematics available are tested designs created by Microchip Technology, Inc. Special attention has been taken to
optimize the performance of the touch controller circuitry in these designs. Different configurations of the existing design
are available, as shown in the various published schematics. Any deviations from any of these designs may impact the
overall implemented design in a negative way. Microchip Technology, Inc. does not recommend any changes or
deviations from what is shown within the published TSHARC schematics. Microchip Technology, Inc. offers free
schematic reviews as a complimentary service to assist design teams in the integration of TSHARC touch controllers.
Application Notes
1) Please contact Hampshire Company to ensure that you have the latest schematic and Bill of Material before proceeding with your
final design. While Hampshire cannot accept any responsibility for your final design, it is recommended that you contact Hampshire
support via telephone or via the support web page before proceeding with your production.
Also, to ensure our ability to support your embedded application of the TSHARC touch screen controller chip we ask that you send
us a copy of your touch screen controller schematics drawings for your customer file. This is helpful if you require support sometime
in the future. We offer this review service free of charge with any of our controller chips. Hampshire does not share this information
with any third party.

2) H2 touch screen connection header.
This header is used to connect variations of 4 or 5 wire sensors. Some or all may be designed into your circuit to ensure
future flexibility to choose a variety of touch screen manufacturers touch screens.
Recommendation: Design in as many of these as you can. See Hampshire’s reference “12V” controller board or contact
Hampshire sales engineer to find ideas how you may maximize your touch screen compatibility matrix.
3) Make sure to keep all analog circuits away from high power and inverter circuits traces. Failure to follow this guideline will reduce
your controller performance and/or accuracy.
4) PS/2 timing can change between different BIOS and PCs. Please make sure you have control of this variable before developing a
PS/2 touch solution. If this control is not in place, other communication protocols are available with the 12s chip and other THSARC
products
5) Jumpers are used to configure the operation mode of the TSHARC-12S controller.
