Newest CapSense Mechanical Button Replacement Family Member
 Enables Complete Matrix Keypad Solution without Software Tools, Firmware Configuration,
Device Programming or System Tuning

SAN JOSE, Calif., 2011년 10월 6일 – Cypress Semiconductor Corp. (Nasdaq: CY), the market leader in touch-sensing, today announced the new CY8CMBR2016 device that enables designers to implement capacitive matrix button systems of up to 4 x 4 buttons without having to write firmware or learn new software tools. A matrix system is a row and column array of buttons typically found in keypad applications in a variety of industrial applications. This is the latest addition to the popular CapSense® Express™ capacitive touch-sensing controller line from Cypress that leverages Cypress’s revolutionary SmartSense™ Auto-tuning algorithm, which completely eliminates the requirement for system tuning and is the only solution that offers run-time environmental compensation.

The CY8CMBR2016 supports industry standard “keypad scan” and “truth table” host interface protocols, enabling customers to leverage their existing host processor firmware. The device also features multi-touch, perfect for matrix applications that require simultaneous button presses to enter various user interface modes. The CY8CMBR2016 operates over a 1.71 V to 5.5 V range making it ideal for a wide range of regulated and unregulated battery applications, and a supply current in run mode as low as 15 uA/button. It is targeted for applications such as security panels, card reader keypads, biometric scanner keypads, fire alarm control panels, thermostats, home appliances as well as any system requiring up to 16 individual CapSense buttons.

SmartSense Auto-tuning dynamically optimizes the capacitive baseline and detection threshold for each button. It adjusts for the optimal capacitance sensing range at power-up and during runtime as environmental conditions change, including temperature, humidity, and noise. Eliminating the need to tune 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 required by competing solutions to address variations in PCBs and overlays.

“This new CapSense Express controller with SmartSense Auto-tuning technology extends the world’s easiest mechanical button replacement portfolio to matrix keypad applications,” said Dirk Franklin, business unit director for Cypress’s CapSense solutions. “The CY8CMBR2016 Matrix Keypad solution enables firmware, hardware, and mechanical engineers to implement capacitive sensing quickly and easily in their application.”

The device offers reliable operation in the harshest sensing conditions and ensures superior immunity to conducted and radiated noise. It also integrates a voltage regulator to address power supply noise as well as filters for any spurious noise.

Cypress’s accompanying design toolbox provides detailed resources to ensure optimal CapSense performance, and advanced system debug features allow customers to take designs directly to production for significantly shorter time-to-market.

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.
