New Cypress CapSense® Express™ Controller is World's Easiest-to-Implement Capacitive Touch Sensing Solution

最終更新日: 2010年8月30日

Solution is First to Deliver Robust Performance without Software Tools, Firmware Configuration, Device Programming or System Tuning.

SAN JOSE, Calif., 2010年8月30日 – Cypress Semiconductor Corp. (Nasdaq: CY) the market leader in touch-sensing, today announced a new CapSense® capacitive touch-sensing controller that enables designers to achieve mechanical button replacement (MBR) without having to write firmware or learn to use new software tools. The new CapSense Express™ device leverages Cypress’s revolutionary SmartSense™ auto-tuning algorithm, which eliminates the requirement for system tuning. Cypress’s accompanying design toolbox provides detailed resources to ensure optimal interface performance, and advanced system debug features allow taking designs directly to production for significantly shorter time-to-market. The controller delivers robust touch-sensing with ultra-low power consumption to extend battery life in a wide range of handheld products, and is ideal for consumer, communication, white goods, lighting, industrial and medical applications.

The hardware-configurable CY8CMBR2044 CapSense Express Mechanical Button Replacement controller operates from 1.7 to 5.5V and offers low overall power consumption with supply current in run mode as low as 15 uA per button and industry-best deep sleep current of 100 nA. The devices offer reliable operation in the harshest sensing conditions and Cypress’s patented CSD (CapSense Sigma Delta) sensing method ensures superior immunity to conducted and radiated noise. With SmartSense auto-tuning, the device dynamically optimizes the baseline and detection threshold and adjusts for the optimal capacitance sensing range at power up and during runtime as environmental conditions change.

"Our new CapSense Express controller with SmartSense auto-tuning technology is the easiest-to-implement capacitive touch-sensing solution available," said Dirk Franklin, business unit director for Cypress’s CapSense solutions. "If you can lay out a PCB, then you can add a capacitive touch interface to your next product. This solution greatly reduces design risk and time to market, simplifying the design-in cycle to a layout task and eliminating the system-tuning step. This device greatly broadens the markets and customers for CapSense, as developers no longer need to be microcontroller (or firmware) experts or have vast tuning experience to easily design out their mechanical buttons."

Eliminating the need to tune the UI subsystem is a significant advantage for large and small manufacturers alike, as it saves engineering time and yield loss that can occur with even slight variations in manufacturing tolerances. This savings is greatly multiplied for customers with a global factory footprint and supply chain. SmartSense auto-tuning can eliminate the need for additional test steps currently required with competing solutions to address the vendor-to-vendor variations in PCBs and overlays.

The CapSense Express device accurately tracks button pushes, even with very closely-spaced sensors. The device also features a built-in failure analysis feature with serial data out for debug, speeding the design-in process. It also integrates a voltage regulator to address power supply noise as well as filters for any spurious noise. The device is available in a small form factor 3 x 3 x 0.6-mm 16-pad QFN package.

About CapSense

Cypress's CapSense touch-sensing solutions have replaced 3.5 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.
