Selection Notes
The host memory controller must explicitly support DDR 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 DDR 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 108 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.
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.
Request a Quote
For W9425G6KH-5 quotation, provide the exact MPN, required quantity, destination, target Date Code if applicable, and any inspection or testing requirements.
For a lower-density DDR SDRAM design, Winbond W9464G6KH-5 provides 64 Mbit rather than the 256 Mbit of W9425G6KH-5. Both are listed as 2.5 V, x16, 66-pin TSOP commercial-grade parts, but controller address mapping, refresh and timing must be checked; this comparison does not establish drop-in compatibility.
