Lattice Rolls Out ispLeverCORE DDR SDRAM Controller IP Core

11/24/2004 - Lattice Semiconductor Corporation (NASDAQ: LSCC) announced the immediate availability of a new ispLeverCORETM IP module, the DDR SDRAM Controller for the LatticeECPTM and LatticeECTM FPGA device families, with speeds validated in-system at 200MHz/400DDR. By comparison, the fastest speed claimed for similar IP in competitive low-cost FPGAs is 133MHz/266DDR.

The Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM) Controller is a general-purpose memory controller that interfaces with industry standard DDR SDRAM. Timing parameters that control specific DDR memory devices can be adjusted by the user through signals that are input to the IP module. In addition, the cores have been tailored to utilized dedicated hardware contained within the LatticeECP/EC devices that facilitate the implementation of high-speed DDR memory interfaces.

"The LatticeECP-DSPTM and LatticeEC FPGAs feature pre-engineered DDR memory interfaces, allowing them to achieve 400Mbps performance -- the only low-cost FPGAs to achieve this performance level," said Stan Kopec, Lattice vice president of corporate marketing. "This new memory controller IP core has been specifically designed to take advantage of that embedded DDR support, delivering high-speed operation in a low-cost fabric. As with all our ispLeverCORE IP, this module has been extensively tested, well documented and is supported by Lattice field and factory application engineers. This release further expands IP support for our LatticeECP and LatticeEC devices. Customers can take advantage of these new cores now to simplify their complex design efforts and speed their time to market," Kopec concluded.

About Lattice ispLeverCORE IP
Lattice ispLeverCORE IP products are highly integrated, modular design blocks that can be reused and easily placed within a programmable logic design. The ispLeverCORE modules implement popular industry-standard functions, commonly known as intellectual property (IP) cores.

Lattice offers a growing line of ispLeverCORE modules, optimized for use with its device families. The ispLeverCORE modules are designed using the highest coding standards, and are extensively tested to meet required functionality and performance. These cores are ready-to-use, well documented, and are supported by Lattice field and factory application engineers. Most ispLeverCORE modules are designed to be parameterizable; i.e., the core can quickly be reconfigured to meet specific system needs.

About the LatticeECP and LatticeEC FPGA Families
The LatticeECP-DSP and LatticeEC FPGA device families are architected to provide the most optimized feature sets combined with the lowest total solution costs of any FPGAs. The new LatticeECP-DSP products, targeted for high-performance DSP applications, provide up to a 50% performance and 75% logic utilization improvement over other low-cost solutions when implementing common DSP functions. The LatticeEC FPGA product family, targeted for general-purpose FPGA applications, is a precise and targeted response to the market's explosive demand for low-cost, architecturally streamlined logic solutions. Through advanced 130nm silicon technology, an optimized architecture and proprietary circuit design, the new Lattice devices lower total solution costs by up to 30% to 50% compared with existing FPGA solutions, and are expected to broaden the adoption of FPGAs within the $20 billion ASIC marketplace.
