Selection Notes
The verified 2.7 V to 3.6 V operating range makes supply-domain compatibility a first screening check when comparing this part with lower-voltage Winbond family variants.
For exact-part selection, compare density, interface, clock ceiling and package together rather than matching only the base Winbond family.
Design Considerations
- Verify that the host I/O supply and logic thresholds are compatible with the 2.7 V to 3.6 V operating range.
- Use 104 MHz as the verified clock ceiling for first-pass controller configuration; apply the exact device timing requirements in the final design review.
Exact Variant and Procurement Notes
The source record lists 2,000 pcs/reel 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.
