SAN JOSE, Calif.--(BUSINESS WIRE)--Feb. 20, 2002

EZ-USB SX2(TM) Provides High-performance, Compact, Low-cost

Solution To Vendors of `Hi-Speed' USB 2.0

Peripherals with Integrated Microcontrollers

Cypress Semiconductor (NYSE:CY) today announced that its EZ-USB SX2(TM) intelligent Serial Interface Engine (SIE) has successfully passed the full suite of compliance tests set by the USB Implementers Forum (USB-IF). The device will be added to the USB-IF Integrators List, signifying to peripheral vendors that the SX2 has met the strict specifications for hi- and full-speed interface devices.

The SX2 SIE provides a 480-Mbps USB 2.0 connection to a peripheral with an integrated microcontroller. The SIE logic handles all standard USB protocol tasks, freeing up the peripheral's microcontroller to handle important application specific tasks.

"EZ-USB SX2's intelligent SIE eliminates the need for developers to learn the protocol details of the USB 2.0 specification," said Jeff Chang, product marketing manager for Cypress's Personal Communications Division. "Simplifying design complexity in this way offers engineers a more gradual USB 2.0 technology learning curve, resulting in shorter design cycles as hi-speed USB is implemented in scanners, printers, networking devices, digital cameras, and other peripheral applications."

The EZ-USB SX2 integrates a USB 2.0 transceiver, a high-speed PLL, an intelligent SIE, a 4-KByte FIFO, and a very simple local bus interface. Its four configurable USB endpoint buffers can be double-, triple- or quadruple-buffered to optimize its performance in any application. The SX2 device was designed to work gluelessly with a range of standard microprocessors and digital signal processors.

USB links PCs to their peripherals in true "plug-and-play" fashion, making PCs much easier to use. The USB 2.0 standard, which transmits data at 480 Mbps, makes the speed of the peripheral-to-PC connection 40 times faster than USB 1.1. Cypress is the world's number one USB supplier, having shipped well over 100 million USB controllers. The EZ-USB SX2 SIE is one element of a broad portfolio of USB 2.0 solutions from Cypress.

Availability and Pricing

Samples of the EZ-USB SX2 SIE are available now. Production volumes are expected to be available March 2002, packaged in a cost-effective 56-pin SSOP and priced at $5.29 in volumes of 10,000 units.
