Automotive TrueTouch®

New standard for performance with AUTOMOTIVE TrueTouch®

Today´s touchscreen devices face tough environments. With displays becoming noisier and devices being used in harsher conditions, providing high touch performance demands a tougher touchscreen controller. Automotive TrueTouch® touchscreen controllers leverage the industry's broadest capacitive touch IP portfolio to deliver a new standard for performance to automotive touchscreens.

Best-in-Class Performance from the Leader in Touch

The Automotive TrueTouch family offers solutions for single touch, two-finger touch, and full multi-touch capability for screen sizes up to 15-inches diagonal. TrueTouch controllers deliver a best-in-class user experience:

  • Unmatched Waterproofing Capability
  • Thick Glove and CapSense® button support
  • Fast Refresh & Scan Rates
  • Low Power Consumption
  • Excellent Accuracy & Multi-Finger Linearity

Unrivaled Touch Leadership

Cypress provides the world's broadest portfolio of touchscreen solutions. Our patents cover categories from panel construction and self- and mutual-capacitance sensing to scanning methods, noise immunity, and finger tracking, spanning every major area of touch sensing innovation. Our continued leadership in the touchscreen space means that we respond to new challenges and market trends with truly innovative solutions.

TrueTouch delivers unrivaled market-leading features. We give you unbeatable protection from noise in a touchscreen system with our proprietary technology. Cypress helps streamline your designs with single-layer sensors that eliminate side bezels and halve the height of your stackup, while slashing your costs. In addition, we deliver truly advanced features like true waterproofing, hover and glove functionality, and 1 mm stylus support, thanks to our unique ability to deliver self and mutual capacitance sensing on a single chip.


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

  • Accurately tracks wet or sweaty fingers
  • Rejects false touches caused by water on the screen
  • Touchscreen doesn't stall or freeze in the presence of moisture

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.

  • Touch detection through gloves up to 5 mm thick
  • Full multitouch functionality with thin gloves (<1 mm), two-finger plus gesture support with thick gloves (>2 mm)
  • No more frozen finger


When designing capacitive touch sense technology into automotive, one needs to keep in mind that the CapSense device exists within a larger framework. Careful attention to every level of detail from PCB layout to user interface to end-use operating environment will lead to robust and reliable system performance.

  • Easy implementation of CapSense and Touchscreen using a single-chip integrated device
  • Reliable CapSense designs that work in harsh automotive environment

TrueTouch Tools: Simplifying the Design Process

Cypress provides the tools you need to complete a capacitive touchscreen design from concept through mass production. Evaluation kits (EVKs) allow you to quickly assess solution performance, while manufacturing test kits (MTKs) and programming and debugging tools help you bring designs to production. TrueTouch Host Emulator (TTHE) software enables you to configure and tune your design, and supports all register-configurable TrueTouch products (Gen4 and later products). 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.

TrueTouch Kits

Cypress offers EVKs so you can evaluate, prototype, and debug complete designs. Kits are available for each product family to support your design. In addition, we offer the Cypress MTK to help you test your sensor hardware both in the prototype and mass production phases; and the TT Bridge Development Kit to program and debug hardware and firmware designs. See the list below for links to our kits.

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.
