Cypress Releases USB Driver For Wind River's VxWorks Embedded Operating System

7/11/2002 - Cypress Semiconductor Corporation (NYSE: CY), the leader in USB technology, today announced the release of its VxWorks USB host driver supporting Cypress’s SL811HS embedded host/peripheral controller. This driver will provide VxWorks developers with the ability to add USB host functionality to a variety of embedded system applications, such as cell phones, MP3 players, network appliances and PDAs.

“Cypress is excited to develop a USB driver on Wind River’s VxWorks—a leading edge real-time operating system (RTOS) and embedded development platform—for their designers,” said Jeff Chang, product marketing manager for Cypress’s Personal Communications Division. “This host controller driver release will enable developers to add USB host functionality to their embedded system designs running the VxWorks RTOS.”

“We are happy to be associated with a premier USB technology leader like Cypress Semiconductor on this USB driver release,” said Ted Hartnell, USB Product Marketing Manager for Wind River Systems Inc. “With today’s aggressive development demands, VxWorks enables designers the resource for real-time updates and to meet their project deadlines, bringing their product to market as quickly as possible.”

Wind River’s VxWorks RTOS supports the Open Host Controller Interface (OHCI) and the Universal Host Controller Interface (UHCI) specifications for USB host controllers, which are typically implemented in a PC architecture and environment. Since Cypress’s SL811HS is a memory-mapped device, the release of this new driver allows the VxWorks host stack to provide USB host support without realizing that there is a non-OHCI/UHCI type host controller. This driver enables engineers to bring their products to market more quickly.

About SL811HS
The SL811HS is Cypress’s first-to-market USB embedded host controller, offering a dual-role port that can function as either a USB host or peripheral supporting both full- and low-speed USB devices.

About VxWorks
Wind River’s VxWorks® RTOS is the fundamental run-time component of the Tornado II embedded development platform, and the most widely adopted RTOS in the embedded industry. VxWorks is flexible, scalable, reliable, and available on all popular CPU platforms.
