Cypress Gen5 TrueTouch Controller Features Noise-Immune Touchscreen Control

TMCnet Contributor
 
Cypress Semiconductor unveiled a Gen5 TrueTouch controller product line featuring noise-immune touchscreen control technology and current standards for optimum performance even when there is noise from various sources.
Gen5 delivers 40 volt peak-to-peak (Vpp) charger noise immunity measured from 1 to 500 kHz with an ultra-thin 0.5-mm cover lens and a finger-size up to 22 mm.
The noise immunity feature allows designers to incorporate ultra-thin, display-integrated stackups, including In-Cell, On-Cell, and direct lamination onto a noisy display. This will help in designing sleeker end products with no missed or false touches.
Other TrueTouch innovations in the Gen5 family include the ability to provide self- and mutual-capacitance sensing on the same chip besides the provision of waterproofing features in real-world conditions, like rain, condensation, or sweat.
This architecture along with an ARM (News - Alert) M-Core processor enables Gen5 to deliver 120Hz refresh rates, and a deep-sleep mode that consumes power of only 4.5 uW. The new devices have ideal sensor pitch that supports standalone CapSense touch-sensing buttons.
Cypress's touch-sensing portfolio includes TrueTouch, CapSense, and TrackPad solutions. The company's IP portfolio offers true, single-layer sensor solutions that reduce touchscreen costs as it provides self and mutual capacitance sensing on the same chip. This allows features like waterproofing, proximity sensing, support for 1-mm stylus, and hover, said officials.
John Carey, senior director of TrueTouch Marketing said, "Cypress continues to lead the industry in touchscreen innovation and Gen5 now eliminates noise from any charger. This removes performance issues resulting in product returns, simplifies touchscreen design, and reduces overall product costs while delivering the best touchscreen user experience."
Recently, DRS Technologies and Cypress Semiconductor announced that DRS will transfer its state-of-the-art Microbolometer technology for uncooled infrared detectors to Cypress for high-volume manufacturing.
The agreement will allow DRS Technologies to continue to improve sensor production by taking advantage of Cypress's advanced manufacturing for significantly reduced wafer costs.
