The automotive solutions offering from Cypress Semiconductor has been expanded with a capacitive touchscreen controller that delivers added water-proofing, glove touch and resistance to electromagnetic interference. The EMI resistance is driven by Cypress’ proprietary AutoArmor technology. The new Automotive TrueTouch CYAT8165X controllers, which target screens up to 8.5“, join a portfolio that includes Cypress’ Automotive TrueTouch CYAT8168X controllers, for screens up to 15“.
“The Automotive TrueTouch CYAT8165X touchscreen controller family delivers a flawless user experience under the broad range of harsh automotive environments in next-generation vehicles,” said Dr. Jing Mu, Senior Director of Automotive HMI Marketing for Cypress. “Our TrueTouch solutions combine with Cypress’s wireless connectivity solutions and automotive MCUs and memories to form the industry’s broadest automotive portfolio, helping our customers to consolidate their supply chains and accelerate their time to market.”
Cypress AutoArmor helps to meet the challenging electromagnetic compatibility (EMC) (CISPR 25) specifications and requirements for chip-level emissions (IEC 61967), conducted (IEC 62132) and radiated (ISO 11452) immunity. AutoArmor uses automatic frequency hopping to prevent false touches caused by EMI from other electronic systems, and it uses TX frequency spreading to reduce electromagnetic emissions.
The Automotive TrueTouch CYAT8165X controller family delivers accuracy and linearity for fingers of different sizes and gloves of various materials and thicknesses, including ski gloves, and automatically switches between glove and finger tracking without requiring the drivers to switch settings. The controllers include up to 48 I/Os with a host processor interface through I2C or SPI, which help improve touchscreen responsiveness. With Cypress’ DualSense technology to execute both self-capacitance and mutual-capacitance measurements in the same device, the family offers water rejection and wet finger tracking for real-world conditions, including the presence of water droplets, condensation or sweat.
