Cypress Semiconductor Corp. (NYSE:CY) introduced the TrueTouch[tm] touchscreen solution based on the PSoC® programmable system-on-chip architecture. The TrueTouch offering includes a single-chip touchscreen solution that can interpret up to 10 inputs from all areas of the screen simultaneously. This capability, known as “multi-touch all point,” enables designers to create new usage models for products such as mobile handsets, portable media players (PMPs), GPS systems and other products.
Examples of applications well-suited for multi-touch all point functionality include keyboard implementations, inputting multiple locations into a GPS, playing video games on a mobile handset, and making multiple adjustments to sound and/or video settings on a PMP.
In addition to the multi-touch all point products, the TrueTouch family includes devices that perform traditional touchscreen functions including interpreting single touches, and gestures such as tap, double-tap, pan, pinch, scroll, and rotate. This combined touchscreen portfolio of solutions is the industry’s broadest. In addition, Cypress will present a webinar entitled “Designing Compelling User Interfaces with Multi-Touch All Point Touchscreen Technology” on June 25 at 9:00 a.m. Pacific Time. Interested parties can register for the seminar at www.techonline.com/learning/webinar/208400682.
Touchscreens have become the user interface of choice for many applications. Touchscreen technology addresses the conflicting demands for smaller products with larger displays by eliminating traditional buttons without sacrificing screen size. They also enable users to manipulate new functions easily and intuitively by interacting directly with content on the screen. TrueTouch devices support “projected capacitive” touchscreens, which offer numerous benefits over touchscreens based on “resistive” technology. These advantages include optical clarity, durability, reliability and cost-effective implementation of multi-touch features.
“Leading customers in a variety of markets, including smartphones, GPS and PMP devices, have worked with us to help define the TrueTouch family,” said Dhwani Vyas, vice president of PSoC products for Cypress. “We are leveraging our established leadership in the capacitive sensing markets to deliver the next generation of touchscreen solutions that offer user interface designers unparalleled flexibility and integration capabilities via the PSoC architecture.”
“Our research clearly indicates that projected capacitive touchscreens for consumer electronics devices are poised for strong growth,” said Jennifer Colegrove, senior analyst, senior analyst and author of the “Touch Screen” 2008 report at market research firm iSuppli. “The TrueTouch family is targeted squarely at this segment.”
Because of the flexible and programmable TrueTouch architecture, customers can choose to work with a wide variety of touchscreen vendors and/or LCD module vendors to create their designs. Other touchscreen solutions are not programmable and require designers to implement a fixed solution with limited materials choices. In addition, the TrueTouch solution utilizes the PSoC architecture’s ability to integrate additional functions such as driving LEDs, backlight control and I/O expansion. These functions, in conjunction with flexible communication options (I2C and SPI), allow for unparalleled system integration for touchscreen systems.
“The TrueTouch family is an excellent example of Cypress’s commitment to provide easy-to-use, cutting-edge solutions for human-machine interfaces,” said Babak Hedayati, sr. vice president of Worldwide Marketing and Applications for Cypress. “Cypress is at the forefront of a number of emerging trends such as this, including intelligent LED lighting, electric mobility, solar power and more.”
The TrueTouch family includes the CY8CTST1xx single-touch devices, the CY8CTMG1xx multi-touch gesture devices and the CY8CTMA100 multi-touch all point device. The products, offered in 32- and 56-pin QFN packages, are expected to sample in August with production in September.
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 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.
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 from 5 cents to 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.
