Key highlights

What matters for BOM review and board bring-up.

  • DDR5 bandwidth
    4800–6400 MT/s for industrial compute and next-gen embedded hosts migrating from DDR4.
  • 1.1 V operation
    Lower voltage than typical DDR4 rails — less heat in sealed or fanless enclosures.
  • Wide-temp industrial grade
    −40°C to +85°C operating range for factory, outdoor cabinet, and edge deployments.
  • WBGA-82 · ×8
    Monolithic 16Gb organization in WBGA-82 — confirm ball map against your DDR5 controller.
  • China-localized supply (CN)
    ChangXin-based die with domestic supply options for CN-labeled programs.

Typical applications

Where this SKU is commonly designed in.
