OR3T55 Datasheet | Agere Systems

Data Sheet June 1999 ORCA® Series 3C and 3T Field-Programmable Gate Arrays Features s s s s s s s s s s s High-performance, cost-effective, 0.35 µm (OR3C) and 0.3 µm (OR3T) 4-level metal technology, (4- or 5-input look-up table delay of 1.1 ns with -7 speed grade in 0.3 µm). Same basic architecture as lower-voltage, advanced process technology Series 3 architectures. (See ORCA Series 3L FPGA documentation.) Up to 186,000 usable gates. Up to 452 user I/Os. (OR3Txxx I/Os are 5 V tolerant to allow interconnection to both 3.3 V and 5 V devices, selectable on a per-pin basis.) Pin selectable I/O clamping diodes provide 5 V or 3.3 V PCI pliance and 5 V tolerance on OR3Txxx devices....
