Selection Notes
W25Q128JWSIQ TR 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.
The exact MPN contains an ordering suffix; keep the complete code unchanged in BOMs, RFQs and purchase orders.
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 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.
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 the Winbond W25Q128JW 128-Mbit, 1.7–1.95 V low-voltage IQ family, compare W25Q128JWSIQ for the same 208-mil SOIC-8 base orderable without this page’s TR shipping label. When a leadless WSON-8 6 x 5 mm board package is required, review W25Q128JWPIQ. Package and PCB constraints still require review; confirm TR carrier details with the supplier and do not confuse this 1.8 V family with 3 V W25Q128JV components.
