Multi-Touch All-Point Offering On a Single Chip
Portable Design News, Monday July 07, 2008
Cypress Semiconductor has announced 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.
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.
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. 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 flexible system integration for touchscreen systems.
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.
