ORCA2 fabric at 400 logic cells
The OR2T04A4S208-DB is a Lattice Semiconductor ORCA™2-series FPGA with 400 logic elements and 11000 usable gates — the fabric is sized for glue-logic consolidation and moderate-density state machines, not for DSP-heavy datapaths. 160 user I/O on the 208-pin package gives plenty of headroom for parallel bus interfaces. 6400 total RAM bits are distributed across the logic array as distributed memory — no dedicated block RAM columns here, so register-intensive designs that need FIFO or small look-up tables will consume logic cells for storage. Budget the RAM into the cell count before floorplanning.
3 V core, 0–70°C commercial temp
Single 3 V supply rail simplifies the power tree — no separate VCCIO or core split needed for this generation. The 0°C to 70°C junction temperature range is standard commercial grade: fine for indoor telecom, test equipment, or industrial control cabinets with forced air, but not for outdoor or under-hood deployment where ambient exceeds 70°C. A four-layer board with a solid ground plane under the core is recommended for signal integrity at the I/O count this part can drive.
Active lifecycle, no second-source on record
Lattice lists the OR2T04A4S208-DB as Active. No official successor or pin-compatible second-source is documented in the available records. The ORCA2 family is a mature node, so availability through standard distribution is stable but not guaranteed for new-design allocation — quote against your BOM quantity to confirm lead time.
