Selection Notes
SPI NAND substitution is not determined by density and package alone; page/block organization, ECC handling and host firmware compatibility should be checked against the exact device documentation before replacement.
The verified voltage, interface and clock values on this page are safe first-pass comparison anchors for the exact order code.
Design Considerations
- Confirm page/block geometry, bad-block handling and ECC expectations from the exact device documentation before firmware qualification.
- Keep the controller I/O domain within the verified 2.7 V to 3.6 V operating range.
Exact Variant and Procurement Notes
The source record lists 96 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 W29N04GVSIAA quotation, provide the exact MPN, required quantity, destination, target Date Code if applicable, and any inspection or testing requirements.
For a lower-density option in Winbond’s W29N-GV parallel NAND family, compare W29N02GVSIAA (2 Gbit) with this 4 Gbit W29N04GVSIAA. Winbond specifies 2.7–3.6 V, x8, TSOP-48 and 2,048-byte pages plus 64 spare bytes for both ordering codes; confirm controller address mapping, capacity needs and firmware support before selecting either device, rather than assuming interchangeability.
