The 134144 bits of block RAM provide local storage for FIFOs or small packet buffers, reducing off-chip SRAM requirements. The core supply voltage is 2.375 V — a single 2.5 V rail with a small LDO will work, but verify the regulator's tolerance against the FPGA's full operating range. The commercial temperature grade (0°C to 70°C) limits this part to indoor, climate-controlled environments; no industrial or automotive variants are listed. Supplied in Bulk (loose units, not tape-and-reel), the OR3L165B7BC432-DB is a surface-mount device. The 432-ball BGA footprint demands a multi-layer PCB with controlled-impedance traces for the high I/O count — a four-layer board is the practical minimum for fan-out. Because the package is a BGA, rework requires a hot-air station with a bottom preheater and a stencil for solder paste.","metaTitle":"OR3L165B7BC432-DB Lattice FPGA, 516 I/O, 244K gates, Active","metaDescription":"Lattice OR3L165B7BC432-DB FPGA from the ORCA OR3LxxxB series. 516 I/O, 244000 gates, 134144 bits RAM, 2.375 V core, 0°C to 70°C.
