384 logic cells in a 5×5 mm QFN
The ICE40LP384-SG32 is a low-power FPGA from Lattice's iCE40 LP family, packing 384 logic cells (48 LABs/CLBs) into a 32-VFQFN exposed-pad package measuring 5×5 mm. The 21 user I/O and 1.14–1.26 V core supply make it a fit for compact, battery-conscious designs where a larger BGA or higher-density part would waste board area and power budget.
Industrial temperature and layout considerations
The 1.14–1.26 V supply rail is tight; a ±3% regulator like the iCE40 LP's own recommended LDO family keeps the core within tolerance. Decouple with a 100 nF ceramic per supply pin plus a 10 µF bulk cap near the paddle via cluster.
Lattice lists the ICE40LP384-SG32 as Active product status. It is ROHS3 Compliant, meaning no restricted substances above the exemption thresholds — no red phosphorus or antimony trioxide in the molding compound, which matters for long-term reliability in humid environments.
