This paper describes the second generation Optimized Reconfigurable Cell Array (ORCA) Field-Programmable Gate Arrays (FPGAs). Architectural Innovations combined with advanced 0.5 m process technology result in a family of high capacity and high speed FPGAs. New types of routing resources are included on the FPGA to ensure routing completion. The first ORCA part in the 2C series, the ATT2C15, contains approximately 2.5 million FETs and has a typical logic capability of about 15,000 usable gates. Preliminary benchmark results confirm the speed and logic capacity of the new parts.>
