Cypress Semiconductor Corp. (NYSE:CY) recently introduced the TrueTouch 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.
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. 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.
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.
