Logic density and I/O for glue-logic integration
The OR2C04A4M84-D: With 11 000 gates and 400 logic cells, this device sits at the lower end of the ORCA2 family — sized for bus bridging, state-machine control, and simple peripheral expansion where a full gate array would be overkill. The 160 user I/O pins give it the headroom to absorb multiple 8- or 16-bit buses and still leave pins for control signals. The 6400 bits of on-chip RAM handle small FIFOs or register files without an external SRAM.
Temperature grade and package handling
This covers most indoor equipment, telecom central-office, and test-and-measurement enclosures, but not extended industrial or automotive ambient ranges. Supplied in Bulk (tube or tray) — not tape-and-reel. For a prototype run or low-volume production this is convenient; for high-volume pick-and-place, confirm the feeder compatibility or request a reeled variant if one exists in the family.
