Cypress's PSoC® CapSense™ Technology Brings Durability And Elegance To Haier Group's Touch-Sensitive Washing Machines And Water Heaters

SAN JOSE, Calif., July 2, 2007 - Cypress Semiconductor Corp. (NYSE: CY) today announced that its PSoC® CapSense™ solution enables the touch sensing interface inside multiple models of Haier washing machines and water heaters. The CapSense solution provides Haier a sleek interface attractive to consumers, while eliminating the deterioration experienced with mechanical buttons and switches.

"Cypress's CapSense is used in our washing machines' touch sensing buttons," said Xu Sheng, Director of Technology Development Department, Haier Washing Machine Business Unit. "Among all white goods, washing machines face the most severe operating environment. Haier has very strict reliability requirements for touch sensing input solutions, and CapSense was selected over other solutions because of its flexibility, reliability, and performance in the presence of humidity, vibration, high temperature and interference."

"Meeting the high reliability standards of Haier, a leading home appliance company, is a resounding endorsement of Cypress's CapSense solution," said Carl Brasek, business unit director for Cypress's CapSense products. "This design win is a testimony to CapSense's reliable sensing operation in harsh environmental conditions."

About CapSense
A single CapSense device can replace dozens of mechanical switches and controls with a simple, touch-sensitive interface. CapSense-based "button" and "slider" controls are more reliable than their mechanical counterparts because they are not prone to the environmental wear-and-tear that affects exposed buttons and switches. Cypress has garnered well over 100 CapSense design wins worldwide in applications that include mobile handsets, portable media players, white goods, computers, printers and automotive, among others.

Capacitive sensing is fast becoming the solution of choice for front-panel display and media control applications. Increased durability, decreased bill of materials (BOM) and a clean, minimalist appearance make this elegant interface attractive to a wide range of designs. With Cypress's CapSense interface, a finger on the interface forms an electrical connection with embedded sensors, which work with the PSoC device to translate data about the finger's presence into various system control functions. The sensor itself is a copper pad on the PCB, not an actual component.  All of the circuitry for controlling the sensor is inside the PSoC device.

Cypress's CapSense solution offers system designers numerous advantages over capacitive sensing products built around modules and sub-assemblies, including increased flexibility, reduced board space and lower cost. Because of the unique PSoC architecture, designers can easily integrate multiple functions (e.g., LED drivers and LCD displays), in addition to capacitive sensing. The PSoC CapSense solution also delivers benefits such as easy communications using either I2C, SPI or USB interfaces, the ability to implement both trackpad (x-y matrix) and linear slider applications with the same device, and the ability to make quick design changes using the flash-based PSoC architecture. In addition, users can complete CapSense designs quickly and easily using pre-configured and verified "user modules" within Cypress's PSoC Designer™ 4.4 Integrated Design Environment (IDE).

About the PSoC Family
PSoC devices are configurable mixed signal arrays that integrate a fast 8-bit microcontroller with many peripheral functions typically found in an embedded design. PSoC devices provide the advantages of an ASIC without the ASIC NRE or turn-around time. A single PSoC device can integrate as many as 100 peripheral functions with a microcontroller, saving customers design time, board space and power consumption. Customers can save from 5 cents to as much as $10 in system costs. Easy to use development tools enable designers to select configurable library elements to provide analog functions such as amplifiers, ADCs, DACs, filters and comparators and digital functions such as timers, counters, PWMs, SPI and UARTs. The PSoC family's analog features include rail-to-rail inputs, programmable gain amplifiers and up to 14-bit ADCs with exceptionally low noise, input leakage and voltage offset.  PSoC devices include up to 32KB of Flash memory, 2KB of SRAM, an 8x8 multiplier with 32-bit accumulator, power and sleep monitoring circuits, and hardware I2C communications.

All PSoC devices are dynamically reconfigurable, enabling designers to create new system functions on-the-fly. Designers can achieve far greater than 100 percent utilization of the die, in many cases, by reconfiguring the same silicon for different functions at different times.  Learn more about PSoC products at and receive free online training at"
