Cypress TrueTouch Touchscreen controllers support Windows 8
February 14, 2012 // Paul Buckley
Cypress Semiconductor Corp's single-chip Gen4 TrueTouch controllers will now support the new Windows 8 operating system from Microsoft Corp. Windows 8 is designed to provide a rich, touch-centric experience for users of tablets, laptops and desktop PCs. The TrueTouch Controllers offer the industry’s best noise immunity, fastest refresh rate, lowest power and highest accuracy. Cypress has worked with Microsoft to ensure compatibility with Windows 8, and is now part of Microsoft’s on-boarding program to prepare for the official release of Windows 8.
The Gen4 family was designed from the ground up to deliver the world’s highest SNR in real world applications. The device is the first and only touchscreen IC that delivers built-in 10 V Tx to drive the touch panel at 10 V. Because SNR is directly proportional to the voltage at which the panel is driven, this feature allows Cypress to offer nearly four times the SNR of the next closest competitor.
In addition to unmatched noise performance, the Gen4 product family claims to offer the industry’s fastest refresh rate of 400 Hz, and has the ability to scan a capacitive touch panel at 1,000 Hz – both industry-best metrics. The level of performance is enabled by the 32-bit ARM Cortex core at the heart of the Gen4 products. The Gen4 family enables unlimited touch performance, while providing the industry’s best accuracy and linearity of 0.2 mm. Gen4 offers these features while boasting the world’s lowest active power consumption of 2 mW, and a deep sleep mode that only draws 1.8 uW with wake-up via address match on the COM port.
