Cypress offers CapSense and TrueTouch controllers in WLCSPs
September 08, 2010 // Paul Buckley
Cypress Semiconductor Corp., is now offering both its CapSense capacitive touch controllers and TrueTouch touchscreen controllers in Wafer-Level Chip-Scale Packages (WLCSPs).
The ultra-small packages enable manufacturers of personal media players, mobile handsets, PC peripherals (printers and mice), and other consumer electronic products to offer end products that are smaller and more attractive to consumers.
The CapSense CY8C207x6A-24FDXC devices are offered in 30-ball packages that measure only 2.2 x 2.3 x 0.4 mm. They offer low power operation (down to 1.7 V) and run-time current consumption for long battery life, along with industry-leading noise immunity and touch sensitivity for up to 25 buttons. The new CapSense controllers also offer Cypress’s SmartSense technology that automatically detects and adjusts for changes in input variables, allowing easier design and manufacturing, along with better performance in the field.
The TrueTouch CY8CTMA300E controller family is offered in a 49-ball, 3.2 x 3.2 x 0.55 mm package. The family offers an integrated analog sensing engine for the industry’s fastest and most accurate touchscreen user experience. The responsiveness allows tracking of multiple fingers simultaneously with precise x-y locations and without user delays or problems with erroneous “ghost” responses. The devices also offer Cypress’s noise immunity, low power consumption and advanced features such as stylus support, hover detection and water rejection.
