Touch Screen

Design Considerations


Cypress AutoArmor™ is a Cypress proprietary technology used to reduce emissions and improve electromagnetic interference (EMI) immunity to meet automotive electromagnetic compatibility (EMC) requirements.

Cypress rigorous testing proves that automotive touchscreen controllers meet the most challenging EMC requirements as specified in CISPR 25, ISO 11452, IEC61967-4 and IEC52132-4.

Dual Sense

Waterproofing is enabled by Cypress proprietary technology.

DualSense technology enables measurement of both self- and mutual-Capacitance touch signals where the self-capacitance sensing allows for touch signal detection when the Mutual-Capacitance signal is saturated by water.

Waterproofing enables safe and robust operation with water droplets, condensation or sweat.

Glove Touch

Glove touch enables the driver to use the touchscreen and change settings without having to take of the gloves.

Cypress proprietary technology such as 5-V TX and multi-phase TX enable detection of small signals required for thick gloves up to 5-mm material thickness.



Cypress’s best-in-class automotive touchscreen solutions enable next-generation cars with feature-rich applications for multi-touch touchscreens and trackpads.

Cypress offers unmatched flexibility and the most comprehensive single-chip touchscreen portfolio for the automotive segment.

The Cypress portfolio offers the best touch performance with advanced features and a range of solutions to meet the most challenging design requirements.

TrueTouch Host Emulator Software

Cypress's TrueTouch Host Emulator (TTHE) is a PC-based software application that allows you to design, configure, tune and debug TrueTouch solutions. It reduces design cycle time by eliminating the need to manually compile source code, generate a firmware image and program the device. TTHE supports all register-configurable TrueTouch products. It interfaces with the controller on a PCB or an FPC through the TrueTouch Bridge connected to a host PC running TTHE. This supports prototyping and debugging throughout various development stages.

TrueTouch Drivers

Cypress's TrueTouch® drivers are easy-to-integrate, high-performance, extensible software drivers that interface between the TrueTouch controller and a touchscreen device's operating system to accurately report touch input. Cypress delivers TrueTouch Driver for Android (TTDA) and that is also part of the Linux Kernel mainline.

Manufacturing Test Kit

Cypress’s TrueTouch® Manufacturing Test Kit enables customers and touchscreen manufacturing partners to test touch panels with Cypress TrueTouch® controllers. The tests performed by this kit are production quality and demonstrate the built-in manufacturing test capabilities of Cypress TrueTouch® controllers. This kit can be used for early touch panel development and prototype testing, as a final production test solution, or as an example/demonstration of how to implement a custom production test solution.
