10/28/2003 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, introduced its new Sequential flow-control (SFC) device family, the latest addition to the IDT portfolio of flow-control management ICs unveiled in June 2003. These new devices provide high-performance data flow management by utilizing a seamless connection to an external double-data-rate (DDR) SDRAM for storing and transferring up to 1 Gigabit of data in a sequential fashion. As important, the IDT SFC devices seamlessly handle all DDR SDRAM interactions, eliminating the need for designers to create circuitry to accomplish this task. In addition, the IDT SFC family can support SDRAM densities of 128 Mbit or 256 Mbit for a single part, allowing up to four memory devices to be connected to each SFC product. To meet the needs of applications requiring greater than 1 Gigabit of memory, the ICs can easily be configured in depth expansion mode so two or more devices can be cascaded to reach multi-Gigabit densities. For designers whose needs for queuing are in the 20-Mbit range, the IDT SFC products offer an economical alternative, as these devices are 50 percent less expensive than off-the-shelf solutions. Furthermore, each SFC device offers a patent-pending technology that allows data to move simultaneously into and out of the SFC part and into and out of the external SDRAM, thus enabling increased data throughput and reduced latency, making the IDT SFC products well suited for communication and networking systems, as well as medical equipment, graphics, and test and measurement systems.
“As Internet traffic continues to increase and the proliferation of graphics and multimedia applications push throughput requirements to new levels, system equipment designers are seeking flexible and cost-effective, data-flow management solutions to address demanding network requirements,” stated Michael Olsen, director of strategic marketing for the IDT flow-control management division. “With these products, we are addressing the needs of customers who desire larger queuing densities within data-processing operations by offering an off-the-shelf, cost-effective and flexible flow-control solution for high-density sequential queuing that replaces previous 'home-grown' or custom solutions and increases throughput and reduces latency.”
Traditionally, high-density sequential queuing of data involved the use of cumbersome and time-consuming "home-grown" semiconductor solutions, including expensive application-specific integrated circuits (ASICs) or field-programmable gate arrays (FPGAs). Implementing an IDT SFC device enables designers to use a smaller, lower-cost FPGA, thereby reducing the complexity and cost of the system implementation and shortening design time.
Rich Wawrzyniak, senior analyst at Semico Research, said, “By combining important functions such as high-speed buffering, switching, multiplexing/de-multiplexing, and random and sequential access, this emerging category of flow-control management ICs is a cost-effective and time-saving solution for system designers who need to overcome data-flow-control issues in their communications equipment designs.”
The architecture of the SFC devices consists of independent read and write ports with associated read and write clocks operating synchronously at up to 166 MHz with 6-Gbps throughput. The device family includes a bus-matching feature, allowing the inputs and outputs to be configured in x36, x18 or x9 bus width (IDT72T6360) or x48, x24 or x12 bus width (IDT72T6480), depending on the device selected. A user selectable error detection and correction (EDC) feature detects and corrects single bit errors when reading from the SDRAM.
Pricing and Availability
Pricing for the new SFC devices is $35 each in 10,000-piece quantities. Devices begin sampling in Q4CY03 with production availability beginning in Q1CY04. Packaging consists of a 17mm x 17mm 324-pin BGA, operating at 2.5-volt core voltage with selectable 2.5-volt or 3.3-volt I/Os.

Flow-Control Management ICs
As a leading provider of innovative products for the communications market, IDT continues to evolve its distinctive competencies in the integration of advanced memory and logic architectures to create a new category of value-added semiconductor devices. The IDT flow-control management devices combine critical functions such as high-speed buffering, switching, multiplexing/de-multiplexing, domain transition and random and sequential access. These devices meet the special requirements of system architects who need to solve data-flow-control issues in their communications equipment designs. The IDT family of off-the-shelf devices replace traditional methods of managing the flow of data streams at different rates within a system — previously accomplished with multiple ASICs, FPGAs, and external SRAM, DRAM or FIFOs.
IDT is a global leader in preemptive semiconductor solutions that accelerate packet processing for advanced network services. IDT serves communications equipment vendors by applying its advanced hardware, software and memory technologies to create flexible, highly integrated products that enhance the functionality and processing of network equipment. IDT accelerates intelligent packet processing with products such as network search engines (NSEs), programmable content inspection engines (CIEs), flow-control management (FCM) ICs and its family of InterpriseTM integrated communications processors.
