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.
Quality & Verification Support
Third-party inspection or testing can be arranged according to customer requirements. Testing fees are borne by the buyer. Additional verification requirements can be discussed before shipment. Physical product, label, packaging, and Date Code photos may be provided where appropriate.

For W9751G8KB-25 quotation, provide the exact MPN, required quantity, destination, target Date Code if applicable, and any inspection or testing requirements.
For a wider DDR2 data interface, Winbond W9751G6KB-25 provides a 32M x 16 organization in an 84-ball WBGA package, versus the 64M x 8 organization and 60-ball WBGA of W9751G8KB-25. Both are 512 Mbit, 1.8 V DDR2 devices, but bus width and package ball count differ; confirm controller connections and board layout before choosing between them.
