Cypress Semiconductor Corp. (NYSE:CY) announced a free online seminar that looks at the benefits gained from adding a capacitive sensing interface to an actual system design. The 60-minute webinar entitled “Using Capacitive Sensing to Solve Real-World Design Problems” will be presented in conjunction with Electronic Engineering Times on Wednesday, March 26 at 9:00 a.m. PDT.
The presenters will give a detailed analysis of the design of an ice-hockey skate blade from Therma Blade, Inc., which uses heat to reduce friction between the blade and the ice surface. Cypress’s PSoC® CapSense(tm) solution allows the heat to be turned on and off using touch sensitive controls. The seminar will show how capacitive sensing solves the challenges of designing a switch that is water-resistant, durable, low-power, reliable, low-cost and can be easily assembled for high volume production.
“This webinar gives designers a real-world example of how to address common design problems with flexible, programmable solutions,” said Babak Hedayati, senior vice president of Marketing and Applications for Cypress. “Cypress has carved out a leadership position in touch sensing based on our ability to help customers such as Therma Blade meet their design objectives.”
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.
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 touchpad (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.
PSoC — Because Change Happens
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. PSoC devices integrate configurable analog and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings. They include up to 32 Kbytes of Flash memory, 2 Kbytes of SRAM, an 8×8 multiplier with 32-bit accumulator, power and sleep monitoring circuits, and hardware I2C communications.
The flexible PSoC resources allow designers to future-proof their products by enabling firmware-based changes during design, validation, production, and in the field. The unique PSoC flexibility shortens design cycle time and allows for late-breaking feature enhancements. All PSoC devices are also dynamically reconfigurable, enabling designers to morph internal resources on-the-fly, utilizing fewer components to perform a given task.
Easy to use development tools enable designers to select configurable library elements for analog functions such as amplifiers, ADCs, DACs, filters and comparators and digital functions such as timers, counters, PWMs, USB, 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.
A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality. Customers can save as much as $10 in system costs. Learn more about PSoC products at www.cypress.com/psoc and receive free online training at www.cypress.com/psoctraining.
