OR3C55 - 3C and 3T Field-Programmable Gate Arrays

Download the OR3C55 datasheet PDF. This datasheet also covers the OR3 variant, as both devices belong to the same 3c and 3t field-programmable gate arrays family and are provided as variant models within a single manufacturer datasheet.

General Description

FPGA Overview 7 PLC Logic 7 PIC Logic 8 System

Key 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 bas.
