On-chip block RAM totals 134144 bits, providing local storage for FIFOs, look-up tables, or small packet buffers without external SRAM. ## I/O count and supply rail With 516 user I/O, this device can interface with wide parallel buses, multiple memory banks, or a dense array of sensors and actuators — a key parameter for BOM fit when the board requires many off-chip connections. The core supply voltage is 2.375 V, a single-rail design that simplifies the power tree compared to multi-voltage FPGAs. ## Industrial temperature qualification The 2.375 V core rail combined with the industrial range means the device's timing margins must be validated across the full temperature sweep; the datasheet's derating curves for I/O output drive and PLL lock range apply at the extremes.","metaTitle":"Lattice OR3L165B7BC432I-DB FPGA, 244K gates, 516 I/O, Active","metaDescription":"Lattice Semiconductor OR3L165B7BC432I-DB FPGA, ORCA OR3LxxxB series, 244000 gates, 516 I/O, 134144 bits RAM, -40 to 85°C.
