New Cypress CapSense devices feature high immunity to noise, low powerThe CY8C20xx7/S CapSense and CapSense Plus controllers from Cypress Semiconductor Corp. feature the company's new QuietZone technology, which provides immunity to radiated and conducted noise. The new devices also feature ultra-low power consumption and high Signal to Noise Ratio (SNR), which provides immunity to radiated and conducted noise.They also offer the industry’s best solution for proximity and water tolerance.
SmartSense Auto-tuning 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.
