Resource budget and device identity
The OR3T806BC432-DB is a Lattice ORCA™3C FPGA with 116000 system gates and 3872 logic cells, putting it in the mid-density range of the family. The 342 I/O count is the headline resource for board integration — count the I/O honestly against your pinout before committing the BOM line. On-chip block RAM totals 63488 bits, which sets the data-buffer ceiling for designs that keep FIFOs or small look-up tables inside the fabric. The 3 V supply rail is a single-voltage core — no separate VCCIO rail is listed, so confirm the I/O bank voltage tolerance against the interfacing logic family.
Temperature grade and design margin
For designs that see 85°C under the enclosure lid or outdoor deployment, the junction-temperature margin is tight; a thermal simulation at the expected airflow is worth running before the layout freezes.
