Cypress develops industry’s first auto-grade capacitive touchscreen

Cypress Semiconductor has announced automotive qualification of its TrueTouch touchscreen and LIN capable CapSense touch-sensing controllers.

The devices, based on Cypress’s flagship PSoC programmable system-on-chip architecture, meet AEC-Q100 standards. The TrueTouch controllers mark the industry’s first automotive-qualified capacitive touchscreen solution.

The CY8C2x345 CapSense controllers pair analog resources with automotive industry standard LIN communication support, making the devices the ideal system controllers to interface with analog and capacitive touch-sensor inputs, and to control backlight LEDs and haptic actuators while communicating over the LIN bus.

The new automotive-qualified TrueTouch controllers – which are available in single-touch, multi-touch gesture and multi-touch all-point offerings – provide the ability to track multiple fingers simultaneously. The TrueTouch solutions are able to control screen sizes up to nine inches. They are designed for use in control panels, GPS and infotainment displays.

Cypress’s TrueTouch solution is the industry’s most flexible touchscreen architecture, allowing designers to implement differentiated features and make last-minute design iterations without board changes. They have a choice of using touch sensors (glass or film) and LCDs from preferred partners, and can develop innovative mechanical designs ranging from flat to curved surfaces of varying thickness.
