Cypress Semiconductor Corp. (NASDAQ: CY) the market leader in touch sensing, today introduced the CY8C20xx7/S CapSense
and CapSense Plus™ controllers with Cypress’s new QuietZone™ technology to combat noise. The new devices offer a number of industry-leading features, including ultra-low power consumption, high Signal to Noise Ratio (SNR) and high immunity to noise. They also offer the industry’s best solution for proximity and water tolerance. More information on the new products is available at
The new CapSense controllers feature QuietZone™ technology, which provides unequaled immunity to radiated and conducted noise. The result of Cypress’s vast experience in replacing over 4 billion buttons, QuiteZone technology delivers best-in-class SNR, ensuring robust touch performance even in extreme noise environments. Its high sensitivity can determine changes in finger capacitance as low as 0.1 pF. A key component of this technology is Cypress’s patented Capacitive Sigma Delta (CSD) Plus™ sensing algorithm.
The CY8C20xx7S devices feature SmartSense™ Auto-tuning that automatically sets and monitors the performance of each sensor and dynamically compensates for noise and environmental variations during runtime to deliver optimal sensor performance and uniform button response. This technology also adapts to manufacturing variations in PCBs, overlays, and tunes out noise generators such as LCD inverters, AC lines and switched-mode power supplies, saving engineers precious development time in implementing capacitive touch designs. It tunes all design parameters for both proximity detection and water tolerance features, with separate fine tuning for proximity distance. SmartSense simplifies the design process and satisfies the rigorous demands of the industrial and white goods markets.
The CY8C20xx7/S also offers the industry’s best proximity detection of up to 30 cm. Its low power enables proximity designs in battery-powered applications, such as “wake-on-approach” for mice that provides lower system power consumption by allowing the device to sleep until a user’s hand approaches. The family also has driven shield capability, which enhances water tolerance capabilities in applications that face the challenges of mist, water droplets or streaming water.
