Cypress introduces new touchscreen controller
Cypress Semiconductor Corp. has expanded its automotive solutions portfolio with a capacitive touchscreen controller that delivers waterproofing, glove touch, and resistance to electromagnetic interference. The Automotive TrueTouch CYAT8165X controller family targets screens up to 8.5 in, and is intended to deliver accuracy and linearity for fingers of different sizes and gloves of various materials and thicknesses, iand it 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' patented 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 seamless performance in 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 is known for high-efficiency MIPS/mW. The controllers are currently sampling, with AEC-Q100 fully automotive-qualified products expected in the first quarter of 2017. They are available in automotive-friendly 100-pin TQFP packages.
