Cypress launches USB 3.0 West Bridge peripheral
controllers for mobile devices
Cypress Semiconductor Corp has introduced the USB 3.0
(SuperSpeed USB) solution specifically built to improve
the performance of mobile handhelds.
Cypress says the new 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 900mA and
also supports mass storage standards such as SD 3.0 and
e-MMC4.4x. It also provides Cypress's new EZ-Dtect feature,
which provides charger and accessory detection without the
need for any external power management device.
According to Cypress, the technology 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
says Cypress.
Cypress also introduced a new 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
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.
"As the world leader in USB, we are pleased to be
the first to bring USB 3.0 performance to the mobile landscape"
said Dinesh Ramanathan, Executive Vice President of Cypress's
Data Communications Division. "Our unique West Bridge
architecture that doubles IOPS performance combined with
the 5-Gbps speed of USB 3.0 will enable mobile devices to
deliver a richer user experience with streaming HD video,
super-fast sideloading and more. We're already working with
multiple top-tier phone and tablet manufacturers who have
shown keen interest in this solution."
Availability
West Bridge Benicia and Bay peripheral controllers are sampling
to lead customers today. The devices are expected to reach
full production by September of 2011.
