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.","metaTitle":"Lattice OR2T04A4S208-DB ORCA2 FPGA, 160 I/O, 0-70C","metaDescription":"Lattice Semiconductor OR2T04A4S208-DB ORCA2 FPGA, 400 logic cells, 160 I/O, 6400-bit RAM, 3 V core, 0-70°C.

In ORCA2 architecture, each logic element maps to roughly one 4-input LUT plus a flip-flop, so the effective LUT count is approximately 400. The 11000 gate figure is a system-gate equivalent for synthesis tool targeting."},{"question":"Does the OR2T04A4S208-DB have block RAM or only distributed RAM?","answer":"It has 6400 total RAM bits, all implemented as distributed memory within the logic array. There are no dedicated block RAM columns.
