Active ORCA3C FPGA with 116K gates and 171 I/O
The Lattice Semiconductor OR3T806S208-DB is an FPGA from the ORCA™3C series, packing 116000 gates and 3872 logic elements into a 208-pin surface-mount package. It delivers 171 user I/O and 63488 bits of on-chip block RAM, making it a fit for glue-logic consolidation or medium-density control-path designs in commercial-temperature environments.
What the parametric specs mean for a board-level decision
The 171 I/O count means this part can handle a 32-bit data bus plus address and control lines with room left for peripheral handshakes — useful when you need to hang a memory controller and a few UARTs off the same die without a CPLD expander. 63488 bits of total block RAM (about 8 KB) is enough for small FIFOs, coefficient tables, or a line buffer in a video scaler; anything larger forces an external SRAM or SDRAM interface through the I/O pins. Runs on a 3 V supply rail — common for 3.3 V logic families, but check that your board's 3.3 V regulator can source the core current without droop; the ORCA3C family's dynamic current scales with toggle rate, so a 1 A-rated LDO is a safe starting point for most designs. If the board sees -20°C or 85°C ambient, this part will drift out of timing.
Package and board-fit: 208-pin surface mount in Bulk
Supplied in Bulk (tubes or trays, not tape-and-reel), so it is suited for prototype runs and low-to-medium volume production where pick-and-place feeders aren't critical. The 208-pin QFP-style package has a standard 0.50 mm pitch — a 4-layer board with via-in-pad is recommended for fan-out, though a well-designed 2-layer board can work if the I/O count stays under 100.
