Selection Notes
W25Q128JWSIQ is a low-voltage memory option with a verified 1.7 V to 1.95 V operating range; do not substitute a 3 V family member without checking controller I/O compatibility.
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 1.7 V to 1.95 V operating range.
- Use 133 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 90 pcs/tube 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.
For this 128-Mbit W25Q128JW IQ, 1.7 to 1.95 V SPI NOR memory, compare W25Q128JWPIQ when a leadless 6 x 5 mm WSON-8 is needed instead of this 208-mil SOIC-8. For a wider leaded 300-mil SOIC-16 assembly, review W25Q128JWFIQ. Winbond lists both within the same low-voltage IQ family, but the footprints and pin access differ and are not direct PCB substitutes.
