ORCA4 fabric — 16192 logic elements and 466 I/O
The Lattice OR4E06-2BM680C is an FPGA from the ORCA4 series, packing 16192 logic elements (2024 CLBs) into a 680-ball BGA. That is 466 user I/O — enough to hang a wide memory bus alongside a parallel sensor array or a dozen SERDES lanes without multiplexing the pins. On-chip block RAM totals 151552 bits, and the equivalent gate count is 899000 — the fabric is sized for mid-density glue logic aggregation or a soft-core processor with peripheral controllers. The core runs at 1.425 V nominal, with the I/O banks supporting separate rails for the interface voltage. This is a commercial-temperature part (0°C to 70°C TA), so it belongs in a controlled indoor environment — telecom central office, lab instrumentation, or a production test head.
Active lifecycle — no end-of-life pressure
Lattice Semiconductor lists the OR4E06-2BM680C as Active. For a BOM that already carries this order code, the supply chain risk is low.
Sizing the fabric against a peer
The closest parametric peer in the Lattice lineup is the LFXP2-17E-6FTN256C from the XP2 family. The OR4E06-2BM680C offers 16192 logic elements vs 17000 — nearly identical density — but the ORCA4 part delivers 466 I/O compared to 201 on the XP2, and 151552 RAM bits vs 282624. The trade-off is clear: the OR4E06-2BM680C is the I/O-rich choice for a board that needs many parallel connections, while the XP2 part carries more block RAM per logic element. Neither is a drop-in replacement — the packages (680-ball vs 256-ball) and pinouts are different.
