New Cypress CapSense® Devices Features Ultra-Low-Power Proximity Detection, Unmatched Water Tolerance and QuietZone™ Technology to Overcome Noise
New Controllers Offer Robust Performance with No System Tuning, Speeding Time-to-Market for White Goods, Home Appliances, Industrial, Medical and Consumer Applications
SAN JOSE, Calif., January 9, 2013 – 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 https://www.cypress.com/go/capsense.
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.
The CY8C20xx7/S is ideal for all application segments ranging from Bluetooth headsets, smart phones and tablets that require lower operating voltages to white goods, small home appliances, TV, monitors and printers which require high SNR for robust touch performance. These devices are also ideal for enabling wake-on approach features in applications such as PC peripherals.
“This family is the premier capacitive touch solution from the market leader,” said Dirk Franklin, Cypress CapSense Business Unit Director. “We have included technology advancements of all kinds in this family, including power management, autotuning, noise immunity, proximity detection and water tolerance. Customers from a wide variety of markets are eager to design with this solution.”

Cypress's CapSense touch-sensing solutions have replaced over 4 billion mechanical buttons in mobile handsets, laptops, consumer electronics, white goods, automotive applications, and virtually any system that has a mechanical button or switch, making Cypress the industry touch-sensing leader. The CapSense portfolio, the industry's broadest and most integrated, enhances industrial design and reliability with the most noise-immune and water tolerant capacitive touch-sensing interfaces, including proximity sensing where direct touch is not required. CapSense proximity sensing provides power savings by activating an interface only when needed while further enhancing industrial designs by only exposing interfaces when necessary. The portfolio ranges from the fixed-function CapSense Express controllers that streamline the transition to a robust touch-sensing interface, to the sophisticated CapSense Plus™ controllers based on the PSoC programmable system-on-chip architecture that can integrate a wide variety of analog and digital system blocks to reduce total chip count and system BOM cost.
