Improved touchscreens deliver versatility & durability
Cypress’ TrueTouch Gen4X touchscreen controller family has been modified to support the company's SLIM (Single-Layer Independent Multi-touch) sensor structure, enabling thin form factors and improving multiple finger and glove tracking.
The TMA445 controller accurately tracks fingers of different sizes and gloves of various materials and thicknesses, including ski gloves. It autonomously switches between glove and finger tracking, provides robust water tolerance and delivers immunity to charger noise of up to 35V peak-to-peak from 1 to 500kHz.
Using DualSense technology to execute both self-capacitance and mutual-capacitance measurements, the family offers excellent water rejection and wet finger tracking for seamless performance in the presence of rain, condensation, or sweat.
The Gen4X family, with its 0.5mm cover lens and a 9mm-wide finger, is based on a 32-bit ARM Cortex M-Core processor that is known for high-efficiency MIPS/mW. The TMA445 controller averages low power consumption of 12mW in active mode and 15µW in deep-sleep mode.
“Gen4X with SLIM delivers the industry’s best single-layer sensor performance,” commented Yi Hang Wang, Director, TrueTouch Marketing, Cypress. “SLIM helps our customers create thin mobile devices at lower costs. With the addition of our superior multi-finger tracking for users wearing gloves, Gen4X is upgrading the touchscreen user experience for mobile devices.”
The Gen4X TMA445 controller with SLIM is now available to lead customers in mobile-friendly 44-pin and 48-pin QFN packages.
