Cypress Adds Two New TrueTouch Capacitive Touchscreen Controllers with Advanced Features for Smartphones, E-Readers and Low-Cost Tablets
CYTT21X/31X Family Provides Best-in-Class Performance, High-Precision Passive Stylus Support and the Ability to Use Single-Layer Sensor Structures
BARCELONA, Spain, March 3, 2015 – Cypress Semiconductor Corp. (NASDAQ: CY) today introduced the TrueTouch® CYTT21X/31X capacitive touchscreen controller family that enables smartphones, e-readers and low-cost tablets to offer multiple advanced features. The CYTT31X controller supports input from a passive stylus with a tip as fine as 2.5 mm, which is essential for writing in languages that require enhanced character recognition for reliable text input, such as Chinese, Korean and Japanese. The CYTT21X controller supports a face detection feature that prevents unintended touches from accidentally hanging up a call. This feature eliminates the need for infrared proximity sensors by using the touchscreen sensor to detect a face 25 mm away, thus cutting bill-of-material (BOM) costs.
The TrueTouch CYTT21X/31X controllers enable ultra-thin smartphone and tablet form factors by leveraging Cypress’s Single-Layer Independent Multi-touch (SLIM®) sensor structures, further reducing BOM costs. The controllers provide best-in-class accuracy and linearity for fingers of different sizes and gloves of various materials and thicknesses up to 5 mm, including ski gloves. In addition, they automatically switch between glove, stylus and finger tracking without requiring the user to switch settings. The family offers industry-leading water rejection and wet finger tracking with best-in-class immunity to electronic noise generated by aftermarket chargers and displays. The CYTT21X/31X controllers include up to 48 IOs with an I2C interface, and up to 44-IOs with an I2C and SPI interface.
“With these new additions to our TrueTouch touchscreen controller family, Cypress now offers our customers in the most cost-competitive markets the most feature-rich solutions for smartphones, e-readers and low-cost tablets,” said Yi Hang Wang, Director of TrueTouch Marketing for Cypress. “Passive stylus support is a key feature for this market, and no other touchscreen solution supports the combination of face-detection, gloved-finger tracking, and SLIM single-layers sensors.”
Cypress is demonstrating its extensive portfolio of TrueTouch touchscreen solutions, its new TrueTouch Fingerprint Reader and its CapSense® touch-sensing solutions at Mobile World Congress 2015 from March 2-5 in Hall 2, Stand 2C26MR at Fira Gran Via in Barcelona.
Cypress’s TrueTouch CYTT21X/31X controllers deliver robust immunity to charger noise of up to 35V peak-to-peak (Vpp). The CYTT21X/31X controllers are based on a 32-bit ARM® Cortex™ M-Core processor that is known for high-efficiency MIPS/mW. With Cypress’s unique and patented DualSense™ technology to execute both self-capacitance and mutual-capacitance measurements in the same device, TrueTouch solutions offer the industry’s best water rejection and wet finger tracking for seamless performance in real-world conditions, including the presence of rain, condensation, or sweat. The TrueTouch portfolio’s unique features are backed by an industry-leading portfolio of more than 100 capacitive touch sensing patents.
The TrueTouch CYTT21X/31X controllers are currently sampling, with production expected in the second quarter of 2015. The controllers are available in mobile-friendly 44-pin, 48-pin and 56-pin QFN packages.
Cypress’s TrueTouch portfolio provides the industry’s best noise immunity, highest SNR, best waterproofing, fastest refresh rates, lowest power consumption, and world’s best accuracy and linearity. TrueTouch solutions provide customers with the flexibility to rapidly develop leading-edge solutions without having to buy turnkey modules. They have a choice of using touch sensors (glass or film) and LCDs from preferred partners and can develop innovative mechanical designs ranging from flat to curved surfaces of varying thickness.
