USB 3.0 come to mobile handhelds with West Bridge peripheral controllers
The West Bridge® Benicia™ (CYWB0263) peripheral controller is a highly optimized Data transfer Offload Engine (DtOE) that enables mobile devices to double the IOPS (Input/output Operations Per Second) throughput, stream high-definition video, “sideload” multimedia content at up to 200 MB per second, and reduce battery charging time by 50 percent with increased charging currents up to 900 mA. The additional performance afforded by Benicia results in a state-of-the-art user experience.
The technology significantly improves the performance of a device during boot, page loading, switching between apps and other tasks that require frequent memory access. It employs the second generation of Cypress’s Simultaneous Link to Independent Multimedia™ (SLIM™ II) architecture, which manages multiple, non-blocking paths between peripherals, memory and the processor to allow maximum data throughput.
This new generation West Bridge controller supports the latest mass storage standards such as SD 3.0 (SDXC with UHS-I) and e-MMC4.4x, enabling faster data access and greater storage capacity. It also provides Cypress’s latest EZ-Dtect™ feature, which provides charger and accessory detection without the need for any external power management device.
The company has also introduced a USB OTG and USB 2.0 solution for mobile devices – the West Bridge Bay™ controller. West Bridge Bay offers the same benefits as Benicia — SD 3.0 and e-MMC4.4x support, EZ-Dtect functionality, and the SLIM™ II architecture — for devices without USB 3.0 capability.
The latest West Bridge peripheral controllers act as data transfer co-processors to an embedded application processor in a handheld, freeing the processor from data-intensive operations. They employ a configurable ARM9™ processor core that enables the devices to act as low power audio co-processors.
