Cypress Semiconductor Corp. (NYSE:CY) announced a free online seminar that examines the emergence of touch screens and the technology behind the increasingly popular interface. The 60-minute seminar entitled “Touch Screens: The Magic Behind Multi-Touch,” will be presented in conjunction with CMP Media’s Electronic Engineering Times on Wednesday, September 19 at 9:00 a.m. PDT.
Touch screens address the conflicting demands for smaller portable electronics with larger displays by eliminating traditional buttons without sacrificing screen size. The webinar includes an overview of multi-touch technology, where a user can touch more than one area of a screen simultaneously to control multiple functions. The presenters will also discuss markets, applications and technical implementations of touch screen technology, and will give an introductory look at Cypress’s PSoC(R)-based CapSense(TM) touch screen solution.
“We have established ourselves as the clear leader in capacitive sensing with our CapSense solution,” said Babak Hedayati, senior vice president of Worldwide Marketing and Applications for Cypress. “This seminar will demonstrate the advantages of CapSense for the many applications that can use touch screens.”
A single CapSense device can replace dozens of mechanical switches and controls with an elegant touch-sensitive interface, and the solution supports touch screens and proximity sensing for superior product differentiation. CapSense-based “button” and “slider” controls are more reliable than their mechanical counterparts because they are resistant to environmental wear-and-tear from temperature change and moisture. 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.
A CapSense interface detects the presence of a conductive object, like a user’s finger, and embedded sensors work with the PSoC device to translate data about the finger’s presence into various system control functions. The sensor is not an actual component, but can be almost any conductive pad, such as copper on the PCB or indium tin oxide. Additionally, the solution can be used with multiple substrates like PCB, flex PCB and PET. Cypress’s CapSense 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 with configurable analog and digital blocks, designers can easily integrate multiple functions (e.g., LED drivers, motor controls, and LCD displays), in addition to capacitive sensing. 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).
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, 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.
