Cypress Semiconductor Corp. (NYSE:CY) announced that the 2007 report, “The Evolution of Cellular Tactical Input,” from IMS Research (Austin, Texas) cited Cypress as the industry leader for capacitive sensing in cellular handsets with more than 70 percent market share. Cypress has shipped over 40 million PSoC® CapSense(TM) devices into mobile phones from across the globe in less than two years, and continues to be designed into new models.
The CapSense solution offers mobile handset and other handheld device manufacturers advantages that are not available with other capacitive sensing products. The unique, reconfigurable PSoC architecture provides unmatched flexibility, enabling last-minute adjustments for new features and functions without having to do major circuit-board layout adjustments. In addition, Cypress’s CapSensePLUS feature lets designers perform additional functions, such as LED control, motor control, power management and more with the same device used for capacitive sensing. This integration saves board space, manufacturing resources, power consumption and inventory requirements. These benefits also apply to end-products in all other markets.
“The CapSense solution has been a major part of the success of the PSoC family, and handsets are particularly well-suited to capacitive sensing,” said Chris Seams, executive vice president of Sales and Marketing for Cypress. “It’s also gratifying to note that we are seeing significant traction in areas outside of handsets as well.”
“Cypress was one of the first companies to recognize and target mobile handsets for capacitive sensing,” said Bill Morelli, mobile technologies analyst at IMS Research. “In our 2007 report on cellular tactile input, Cypress is noted as the clear leader in capacitive touch solutions for this market.”
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 hundreds of 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 only 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(TM) 4.4 Integrated Design Environment (IDE), and experience real-time sensor tuning and monitoring with PSoC Express(TM) visual embedded system design tool.
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 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 8×8 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.
