LatticeEC FPGA and ispMACH 4000 CPLD Power RAD's Optimux Multiplexers

8/31/2005 - Lattice Semiconductor Corporation (NASDAQ: LSCC) announced that RAD Data Communications has selected the LatticeECTM FPGA as well as the ispMACHTM 4000 CPLD for its advanced Optimux-T3 multiplexer. The Optimux-T3 multiplexer provides a highly cost-effective and simple solution for transporting multiple E1 and T1 links, as well as a combination of E1 and T1, over a standard T3 electrical signal or fiber link. The Optimux provides flexible solutions to meet the specific requirements of a broad range of applications. The Lattice devices manage the cross connect on the E1/T1 platform, and provide the interface logic to the Framer as well as other circuits.

"We found the Lattice FPGA and CPLD devices were an extremely cost effective design solution for our product," said Ernest Leizer, Team Leader of the ATM Group at RAD. "Of course, we evaluated devices from several suppliers, and found the price/performance ratio and I/O combination of the Lattice devices ideal for our project. In fact, we are now looking at the new LatticeXPTM non-volatile FPGA for use in future designs in order to eliminate the boot PROM."

"Just a year after their introduction, LatticeEC and LatticeECPTM FPGAs are being used in a remarkable variety of designs around the world," said Stan Kopec, Lattice vice president of corporate marketing. "Customers such as RAD Data Communications are discovering that our low cost FPGAs deliver high performance. And now, with the recent introduction of the non-volatile LatticeXP FPGAs, customers can take advantage of the benefits of non-volatility without having to forfeit SRAM technology," Kopec concluded.

About the LatticeECP-DSPTM and LatticeEC FPGA Families
The LatticeECP-DSPTM 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.

About LatticeXP FPGAs
Non-volatile LatticeXP FPGAs deliver the benefits of instant-on operation, excellent security and a single-chip implementation, and provide cost-effective alternatives to traditional SRAM-based FPGAs and their associated boot memories. The ispXPTM technology used in the LatticeXP devices combines SRAM and non-volatile Flash memory to deliver an FPGA that is both non-volatile and infinitely reconfigurable. The SRAM-based memory cells control the operation of the device logic and are loaded from the on-chip Flash memory in less than 1mS at power-up -- providing instant-on capability -- or on user command. Unlike SRAM-based FPGAs, the LatticeXP device does not require an external boot memory and so provides a single-chip solution with the associated benefits of reduced board area and simplified system manufacture. The absence of an external boot device also eliminates the need for an external bit-stream at boot up and the possibility of bitstream snooping, a major security concern with SRAM FPGAs. Security features prohibit bit-stream readback from the SRAM and Flash sections of the devices to further enhance security.
