Oztek Selects LatticeXP Device for CPLD and FPGA Applications

11/8/2005 - Lattice Semiconductor Corporation (NASDAQ: LSCC) announced that design services firm Oztek Corporation has chosen the LatticeXPTM FPGA for use in several distinct designs. "In one case, we designed a power supply for a high-end instrumentation product," said Dave Zendzian, Oztek co-founder and vice president of Engineering. "The power supply is comprised of 16 dual output cards in the motherboard, as well as a microprocessor. The design originally called for a CPLD, but the amount of logic in the design was more than the CPLD could comfortably accommodate. We chose to substitute a LatticeXP FPGA for the CPLD. There are multiple interfaces in the design, including SPI, serial and A/D converters. The LatticeXP device provides a seamless bridge to these interfaces, and easily handles the amount of logic required," Zendzian continued.

"We faced a similar challenge in the design of a power control system for a robotics application," said Zendzian. "Again, 'logic creep' made the use of a CPLD impractical. Because the LatticeXP device is non-volatile, it was very easy to migrate the design because the LatticeXP FPGA requires no external boot PROM. While the design consumed virtually 100% of the CPLD, just 20% of the LatticeXP resources were needed. And the cost of the Lattice FPGA was about half that of the CPLD," Zendzian noted.

"Our most recent design, a hand-held, battery-powered instrumentation device, takes full advantage of the LatticeXP FPGA features," said Zendzian. "The design requires a lot of logic, dual port RAM and PLL features. The LatticeXP device is used to implement a UART, a DSP bus interface and instrument control functions. Because the device is portable and battery-powered, size and power consumption are critical considerations. The LatticeXP FPGA is non-volatile, so it can be shut down to save power using the Sleep mode feature, and boot up takes only milliseconds. Non-volatility means a single-chip solution, saving space as well as reducing our design cycle. We've also been very pleased with the local Lattice support; Lattice people have been a genuine partner in these designs, and their expertise has been invaluable," Zendzian concluded.

"The LatticeXP device is the only non-volatile FPGA that exploits the full potential of Flash plus SRAM technology," said Stan Kopec, Lattice vice president of marketing. "That combination makes our LatticeXP devices the only full-featured non-volatile FPGAs that are infinitely reconfigurable and that can be transparently upgraded in the field. At the same time, our customers receive the traditional benefits of non-volatility, including high security and a single-chip, space saving solution," Kopec concluded.

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.
