The Lattice OR2T10A5S208-DB is an ORCA™2 family FPGA delivering 28,300 usable gates with 1,024 logic elements (256 CLBs) and a 12,300-gate density per the functional description. It provides 163 user I/O pins and 16,384 bits of on-chip block RAM, running from a 3 V supply rail — typical for mid-1990s Lattice ORCA2 designs targeting glue-logic consolidation or medium-scale state machines in telecom and industrial control backplanes.
Supplied in a Bulk (tray or tube) package, surface-mount — the 208-pin footprint likely matches a standard PQFP or similar fine-pitch quad flat pack. The 163 I/O count means roughly 80% of the pins are user-assignable; the rest are power, ground, and configuration pins. For PCB layout, the 3 V core supply requires a dedicated plane or star trace with local decoupling per the manufacturer's guidelines — the ORCA2 family's internal routing capacitance draws transient current during logic transitions.
Lifecycle and sourcing posture
Lattice Semiconductor lists the OR2T10A5S208-DB as Active. For volume procurement, the 208-pin surface-mount package and 3 V supply are the fit gates — verify the BOM's I/O count and RAM footprint match the 163 / 16,384 figures before committing.
