Benicia | Cypress Semiconductor


This product is Not Recommended For New Designs (NRND). Cypress recommends using the EZ-USB FX3S family instead.

The Cypress's West Bridge® Benicia™ peripheral controller offers a revolutionary architectural enhancement in embedded applications. Benicia is the industry's first USB 3.0 solution specifically built for mobile applications.  With the support for the latest SD 3.0 (SDXC with UHS-I) and eMMC 4.41 standards, Benicia provides improved storage performance to enhance user experience.

The SLIM® II architecture offloads data transfer from the main processor, providing uninterrupted and simultaneous data flow among processor, storage and USB.  To facilitate faster battery charging with increased USB 3.0 power regulation, the built-in EZ-Dtect™ feature provides charger and accessory detection without the need for any external power management device.
