Cirrus Logic develop an advanced product portfolio of haptic and sensing integrated circuits (ICs)

With the goal of elevating the user experience for a wide range of consumer devices, Cirrus Logic (Nasdaq: CRUS) is leveraging its technology leadership in low-power, low-latency mixed-signal processing to develop an advanced product portfolio of haptic and sensing integrated circuits (ICs). Cirrus Logic’s haptic products and sophisticated haptic feedback technology enable sleeker, more robust end products with fewer mechanical controls for new responsive and immersive user experiences.

 

Already a leader in haptic technology for smartphones, Cirrus Logic is expanding its haptics and sensing expertise to provide an immersive touch experience for applications in automotive, augmented and virtual reality, gaming, personal computers and wearables. The new Cirrus Logic CS40L25 family of boosted haptic drivers enables OEMs to create customized user experiences beyond the single-action response of today’s mechanical buttons.

 

“Consumer devices have become slimmer and more display-driven, and advanced haptics are evolving to offer consumers a richer, more tactile experience,” said Harsha Rao, Cirrus Logic manager, Haptics and Sensing. “Cirrus Logic’s haptic solutions feature low-latency, boost voltage and closed-loop control algorithms that enable customized waveforms to trigger a variety of fast, unique haptic feedback responses. Whether it’s an immersive first-person gaming experience or a distinct smartphone vibration that identifies the caller, our advanced haptics can create a crisp click that just feels better to the user.”

 

Beyond the smartphone

 

The new haptic solutions from Cirrus Logic can help create context-aware “virtual” buttons for almost any surface. By eliminating mechanical buttons, product designers can create cleaner, sleeker industrial design aesthetics with no button “bumps.” Many smartphone designers are leading this behind-the-screen design evolution to increase haptic feedback solutions by replacing peripheral button functions. Automobiles, PCs, wearables and game controllers are also moving beyond traditional button interfaces to incorporate non-mechanical haptic feedback.

 

Cirrus Logic CS40L25 product features and availability

 

Cirrus Logic’s CS40L25 products integrate a high-performance haptic driver, a digital signal processor and a boost converter. The devices are resonance-aware, drive high-performance linear resonant actuators (LRAs) and voice coil motors (VCMs), and enhance user experiences by supporting unique/pre-stored haptic waveforms. Ultra-low latency provides real-time control of the haptic motor. This provides users with a more immediate sensation or response. Closed loop algorithms maximize LRA effectiveness and enable strong and consistent haptics with a crisper, less “buzzy” effect.
