21ic News Cypress Semiconductor Corporation has announced the launch of a TrueTouch® Gen4X touch screen controller. The controller has a face detection feature designed to prevent accidental touches that cause the phone to hang up unexpectedly. The face detection feature of the new Gen4X TMA445A eliminates the need for infrared sensors in smartphones, reducing material costs. In addition, the TMA445A offers Cypress's industry-leading multi-finger glove touch capabilities. This article refers to the address: http:// The TrueTouch Gen4X TMA445A uses the Cypress Single Layer Independent Multi-Touch (SLIM®) sensor architecture to reduce the thickness of your smartphone. The controller has the industry's best precision and linearity for different sizes of fingers and gloves of all materials and thicknesses, including ski gloves. In addition, it automatically switches between finger and glove modes, eliminating the need for the user to manually switch settings. Gen4X has industry-leading water resistance and wet finger tracking capabilities, as well as the industry's best anti-jamming capabilities for third-party chargers and display noise. The TMA445A has the fastest refresh rate in the Gen4 family, resulting in superior touch screen performance. Cypress's TrueTouch Marketing Director Wang Yihang said: "Cypress continues to invest in Gen4X touch screen controllers to bring better smartphone system value and performance to China and other cost-sensitive markets. Our latest control The device improves the end-user experience by supporting face detection and glove touch, and its SLIM architecture allows our customers to create thinner, more beautiful mobile devices." Cypress's TrueTouch Gen4X series is immune to charger noise and is capable of withstanding 35V peak-to-peak (Vpp) noise in the range of 1 to 500kHz under 0.5mm and 9mm finger test conditions. Cypress's proprietary DualSenseTM patented technology enables self-capacitance and mutual capacitance sensing algorithms on the same chip, giving the industry the industry's best waterproof and wet finger tracking performance in rain, dew and sweat Work smoothly in the real environment. The unique features of the TrueTouch product line are derived from Cypress's industry-leading patents of more than 100 capacitive touch sensors. The Gen4X family features a 32-bit ARM® CortexTM M core processor known for its high MIPS/mW performance. The TMA445A controller has an average power consumption of as low as 12 mW in active mode and 15 uW in deep sleep mode. Availability The Gen4X TMA445A controller supporting SLIM is now available and is expected to be in volume production in the fourth quarter of 2014. The controller is available in 44-pin and 48-pin QFN packages for mobile products.
