Cypress has announced the Automotive TrueTouch CYAT8165X touch controller that is for displays up to 8.5″ and supports operation with gloves.
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 is intended to deliver 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.
The controllers are based on a 32-bit ARM Cortex M-Core processor that Cypress highlights for high-efficiency MIPS/mW.
The Automotive TrueTouch CYAT8165X controllers are currently sampling, with AEC-Q100 fully automotive-qualified products expected in the first quarter of 2017. The controllers are available in automotive-friendly 100-pin TQFP packages.
