CHERRY XTRFY Tops Keyboard Performance Benchmarks with SPARK Microsystems Low Energy UWB Wireless Connectivity

CHERRY XTRFY K63W Pro keyboard – the world’s first with LE-UWB – achieves 8K responsiveness and interference-free gaming with long battery uptime

MONTREAL--(BUSINESS WIRE)--SPARK Microsystems, a Canadian fabless semiconductor company specializing in next-generation short-range wireless communications, today announced that computing peripherals pioneer CHERRY has selected SPARK LE-UWB™ (Low Energy UWB) wireless connectivity for its newest gaming keyboard.

The CHERRY XTRFY K63W Pro gaming keyboard is the world’s first to feature LE-UWB™ technology. Its performance profile is unequaled. Features include:

• True 8000 Hz (8K) wireless polling rate. Optimizing speed and latency with responsiveness up to 8 times every millisecond, SPARK LE-UWB™ enables faster transmission of every keystroke.
• Smooth, reliable connectivity in frequency spectrum that’s uncongested by Bluetooth, Wi-Fi and narrowband signal noise. SPARK LE-UWB™ ensures a highly stable connection, even in crowded wireless environments.
• Longer gameplay without interruption. Power-efficient SPARK LE-UWB™ technology helps keep gamers in the action for up to 1100 hours between battery recharges.

The CHERRY XTRFY K63W Pro gaming keyboard is a low-profile, esports-optimized compact (70%) design with premium gasket construction and CHERRY’s signature MX LOW PROFILE 2.0 mechanical switches. It includes a high-capacity 6000 mAh battery for extended playtimes made possible with LE-UWB™. A wired-connectivity option enables seamless in-play charging.

“CHERRY XTRFY’s heritage of breaking design barriers is our differentiator, and SPARK has equipped us to achieve an important new milestone with connectivity that outperforms legacy wireless,” said Joakim Jansson, Director of Product Management at CHERRY. “For competitive gamers, that means ultra-responsive, power efficient wireless performance engineered to keep pace with the speed, precision and low-latency demands of modern esports.”

“Gamers from all corners of the world consider CHERRY the gold standard in keyboard and switch technology. 60 million keyboards and counting are built upon CHERRY’s innovations,” said Abdul Alameh, Product Director, SPARK Microsystems. “By embracing LE-UWB™ connectivity, CHERRY has fundamentally elevated gaming technology yet again.”

The CHERRY XTRFY K63W Pro will be available for purchase in stores and online starting July 2, 2026. For more information, visit CHERRY’s website.
