About FPGA Orca

Something about FPGA from Lucent Technologies

Field-programmable gate arrays (FPGAs) are versatile logic ICs that can be programmed to perform a desired function by the customer. When compared to masked-programmable gate arrays, FPGAs allow designers to bring products to market in far less time. This time-to-market advantage has fueled a 53% annual growth rate for FPGAs in the last three years, making it the largest growing segment in all of the electronics industry.

In 1997 we are introducing the ORCA OR3C/OR3T series - a new generation of SRAM-based FPGAs built on the successful OR2C-A/OR2T-A FPGAs from Lucent Technologies Microelectronics Group, with enhancements and innovations geared toward today's high-speed designs and tomorrow's systems on a single chip.

Designed from the start to be synthesis friendly and to reduce place-and-route times while maintaining the routability of the ORCA OR2C-A/OR2T-A devices, the OR3C/OR3T series more than doubles the logic available in each PFU and incorporates system-level features that can further reduce logic requirements and increase system speed. OR3C/OR3T devices contain many new patented architectural enhancements and are offered in a variety of packages, speed grades, and temperature ranges.

In 1996 we introduced two enhanced versions of the ORCA series of FPGAs: the OR2C-A series (5 V operation), and the OR2T-A series (3.3 V operation). In addition to being processed using advanced 0.35 µm processing, these devices also include many new features, such as synchronous single-port and dual-port RAM and enhanced multiplier support. Lucent's complete ORCA Series FPGAs offers 3,500 - 340,000 usable gates and up to 608 user I/Os in 0.6 µm, 0.5 µm, 0.35 µm, 0.3 µm, and 0.25 µm CMOS technologies. ORCA FPGAs offer a real alternative to low-end gate arrays with their area-efficient architecture and performance. The SRAM-based 0.6 µm and 0.55 µm ATT3000 Series FPGAs, which feature toggle rates up to 270 MHz, are a direct second source to the Xilinx XC3000 FPGAs and are pin-for-pin and speed compatible with the Xilinx XC3100 FPGAs.

Both the ORCA and the ATT3000 Series FPGAs are supported by PC and workstation software from popular third-party software tool vendors, such as Synopsys, Mentor Graphics, Viewlogic, Cadence, Exemplar Logic, Synplicity, and many others. Lucent also supplies map/place/route implementation software, known as the ORCA Foundry Development System, to support both series of devices.
