Cypress Unveils Windows CE Driver for USB Embedded Host Controllers

3/26/2004 - Cypress Semiconductor Corp. (NYSE: CY), the market share leader in USB, announced a Windows® CE driver for its EZ-HostTM and EZ OTGTM embedded host controllers. The driver supports Windows CE.NET v4.2 and Windows Mobile 2003 operating systems and works with the existing USB stack and class drivers provided in Windows CE to instantly enable USB Host and OTG-based products that communicate with millions of existing USB peripherals.

"Windows CE includes the most popular USB class drivers for connecting to human interface devices, mass storage peripherals and printers. Cypress’s Windows CE driver vastly expands the number of devices with which EZ-Host and EZ-OTG-based products can connect," said Brian Booker, manager for USB embedded host products in Cypress’s Personal Communications Division. "With the OTG protocol fully supported and tested for compliance in both the silicon and driver, manufacturers of Windows CE-based devices can now easily create products that conform to the USB On-the-Go industry specification."

The host port interface of Cypress’s EZ-OTG and EZ-Host controllers is used for 16-bit high-performance data transfer. The driver supports various serial interface engine and port combinations of the chips, enabling a broad range of host, peripheral and OTG devices. Complete software source code and documentation are available via download from the Cypress web site at

Featuring 16-Bit RISC controllers, large memory and low power, Cypress’s EZ-Host and EZ-OTG embedded controllers operate as either hosts or peripherals, depending on the application. EZ-Host (CY7C67300) is a multi-port controller featuring two individually configurable two-port serial interface engines (SIEs) and a configurable I/O block that can connect to numerous standard interfaces. The product is targeted at wired devices, ranging from DVD players, set-top boxes, Internet appliances and print servers. EZ-OTG (CY7C67200), based on the USB On-The-Go (OTG) protocol, enables direct connectivity between portable devices, such as cell phones, PDAs, video and still cameras, MP3 players and mass storage peripherals.
