CY and the Beast
AN JOSE, Calif., April 10, 2000 -- Cypress Semiconductor Corporation (NYSE:CY) today eclipsed all other FIFO (first-in, first-out) offerings with the introduction of the "Beast™" family of 80-bit-wide devices. The new FIFOs offer unparalleled bandwidth of over 30 Gigabits per second (Gbps), more than twice that of any competitor. The family breaks new ground, not only operating at 200 MHz with 5 Megabits of density but at a new low voltage offering of 2.5 V. The Beast FIFO is consistent with Cypress's strategy to maximize specialty memory bandwidth, a critical attribute in bandwidth-hungry datacom applications, including the routers and switches that power the Internet.
"Cypress has continuously pushed the bandwidth boundaries in specialty memories, as opposed to focusing on density," said Geoff Charubin, director of specialty memories. "We were the first to hit the 10 Gbps plateau with the 133 MHz x36 FIFO and the QuadPort™ RAM. We are again the first to break 30 Gbps with the Beast FIFO. We have clearly built a leadership position in this area, and we plan to continue to raise the bar."
Beast FIFO Features
The Beast offers bus matching on both the input and output ports, allowing the x80 device to be configured as x40, x20, x10, or any combination of widths. The x80-bit interface can easily accommodate the 64-bit-wide interfaces of processors and DSPs. The Beast FIFOs provides the ability to add extra parity bits or additional control information bits to be buffered with the data bits. This allows enhanced fault tolerance in systems and offers a convenient method for out-of-band signaling. Designers can easily interface buses of different widths, while utilizing the entire depth of the FIFO. Additionally, the two independent ports can operate at different data rates, providing seamless interfacing between multiple, disparate clock domains. No external logic is required.
The Beast family extends to 5 Megabits of memory-buffering capability, making them the largest FIFOs available. The devices are ideal for bandwidth-hungry local area networks (LANs), wide area networks (WANs), and storage attached networks (SANs), all of which are used to transfer and store the rapidly expanding amount of data, voice and video traffic that travels over the Internet. (Bandwidth equals the word width of a device, times the number of ports, times the clock speed.)
