Logic fabric and memory headroom
The OR3L165B7BC432I-DB: Built on Lattice's ORCA™ OR3LxxxB series, this FPGA integrates 244000 gates and 8192 logic cells — a density tier suited for glue-logic consolidation, state-machine control, and moderate-throughput datapath processing in industrial and communications equipment. 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.
