Exact-Part Selection Insight
The exact part combines 64Mbit capacity with a SPI interface at up to 120MHz. Addressing, page/erase behavior and firmware timing must therefore match this density and bus mode; a same-family device with a different density is not automatically a drop-in data-layout replacement.
Selection Notes
- Package: SOP-8-208mil
- Supply voltage: 2.7V~3.6V
- Memory capacity: 64Mbit
- Interface: SPI
- Clock Frequency: 120MHz
Application Fit
This exact part is appropriate for designs that require a memory device with the confirmed package and electrical/function parameters above. Final fit depends on the surrounding circuit, interface, thermal and mechanical requirements of the target design.
Design Considerations
Confirm the available supply rail stays inside the stated operating range, including startup and transient conditions.
Verify interface voltage levels, bus topology and timing/data-rate requirements against the rest of the system.
Use the exact SOP-8-208mil footprint/package definition when checking PCB land pattern, assembly clearance and sourcing equivalence.
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. After an order is placed, physical product, label, packaging, and Date Code photos may be provided where appropriate.
Request a Quote
To request a quotation, provide the manufacturer part number, required quantity, destination, target Date Code if applicable, and any testing or inspection requirements.
For a current production-series comparison, review GD25Q64ESIG. GigaDevice lists GD25Q64E as MP at up to 133 MHz, compared with GD25Q64C (NR, up to 120 MHz). Both families include 64-Mbit 2.7–3.6 V SOP8 208-mil options. Do not assume drop-in compatibility: verify command set, timing, programming behavior and firmware before selecting.
