16-bit DSP core — active production
The TMS320BC51PQA80G4: ROHS3 compliant per the manufacturer's classification, so it ships without restricted substances under the EU RoHS directive — no separate compliance documentation is needed for EU-market builds.
Bulk packaging — volume or prototype
Supplied in bulk (tray or tube, not tape-and-reel), which suits both low-volume prototyping and high-volume assembly lines that handle loose parts. The package is a standard QFP footprint — the 0.50 mm pitch demands a four-layer board for fan-out; two-layer breaks out only the outer rows.
