Cypress Korea, a market leader in touch sensing (www.cypress.com), has announced the CY8C20xx7/S CapSense® and CapSense Plus™ controllers featuring Cypress's new QuietZone™ technology for noise immunity.

The newly announced devices deliver numerous industry-leading features including ultra-low power consumption, high signal-to-noise ratio (SNR), and superior noise immunity. These new devices also provide industry-leading solutions for proximity detection and water tolerance capabilities. More detailed information about the new products is available at www.cypress.com/go/capsense.

The new CapSense controller features QuietZone™ technology, which provides excellent immunity to radiated and conducted noise. As a result of Cypress's accumulated experience replacing over 4 billion buttons, QuietZone technology delivers the highest signal-to-noise ratio while ensuring robust touch performance even in extremely noisy environments. The high sensitivity of this technology can detect changes as low as 0.1 pF in finger capacitance. Furthermore, the core element of this technology is Cypress's patented Capacitive Sigma-Delta (CSD) Plus™ sensing algorithm.

The CY8C20xx7S device features SmartSense™ Auto-tuning, which automatically configures and monitors the performance of each sensor and dynamically compensates for noise and environmental changes during runtime to deliver optimal sensor performance and uniform button response. This technology also adapts to manufacturing variations in PCBs and overlays, freeing engineers from having to pay attention to noise generators such as LCD inverters, AC lines, and switch-mode power supplies when implementing capacitive touch designs, thereby preserving their valuable development time. In addition, it calibrates all design parameters for proximity sensing and water tolerance features with separate fine-tuning for proximity distance. SmartSense simplifies the design process and meets the rigorous requirements of industrial and white goods markets.

Additionally, the CY8C20xx7/S provides industry-leading proximity detection of up to 30 cm. The device's low power enables proximity designs in battery-powered applications such as "wake-on-approach" for mice, which put the device to sleep until a user's hand approaches. This product family also drives shielding functionality to enhance water tolerance in applications facing challenges such as fog, water droplets, or flowing water.

The CY8C20xx7/S is suitable for all application areas ranging from Bluetooth headsets, smartphones, and tablets that require low operating voltage, to white goods, small appliances, TVs, monitors, and printers that demand high SNR for robust touch performance. These devices are also suitable for enabling wake-on-approach functionality in applications such as PC peripherals.

"This product family represents the best capacitive touch solution Cypress has delivered as an industry leader. Cypress has incorporated all kinds of technological advances in this product family, including power management, auto-tuning, noise immunity, proximity detection, and water tolerance. Customers across diverse markets are looking forward to designing with this solution," said Lim Young-do, Managing Director of Cypress Korea.

Product Availability and Starter Kit:
The CY8C20xx7/S CapSense controller product family is currently in production in 16-QFN, 30-WLCSP, 24-QFN, 32-QFN, 48-QFN, and 16-SOIC packages. The CY8C20xx7/S controller can be easily evaluated using the AEK-CY8C20xx7 QuietZone Starter Kit from Artaflex. Based on the CY8C20247S?24LKXI, the starter kit enables proof-of-concept development by direct connection to the target design board. More details about the kit are available at Cypress's Design Partner Solutions web page (www.cypress.com/?rID=69299) and the Artaflex website (www.artaflex.com).
