Selection Notes
The host memory controller must explicitly support DDR2 SDRAM; do not substitute across DDR generations solely because density or package appears similar.
Controller voltage, clock target and package footprint should be screened together, with organization and detailed timing confirmed from the exact device documentation before layout or substitution.
Design Considerations
- Configure the memory controller for DDR2 SDRAM, not merely for the same density.
- Validate controller timing and power-rail compatibility at the intended operating point before PCB release.
Exact Variant and Procurement Notes
The source record lists 209 pcs/tray for this exact order code.
Preserve the complete manufacturer part number in BOMs, RFQs and purchase orders; adjacent Winbond family variants may differ in package, voltage, speed or ordering suffix.
