Exact-Part Selection Insight
The exact part combines 256Mbit capacity with a SPI interface at up to 133MHz. 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: WPDFN-8(6×8)
- Supply voltage: 2.7V~3.6V
- Memory capacity: 256Mbit
- Interface: SPI
- Clock Frequency: 133MHz
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 WPDFN-8(6×8) footprint/package definition when checking PCB land pattern, assembly clearance and sourcing equivalence.
