The verdict is based on public parameters only (capacity/interface/package/pins/speed); timing margins, temperature grades, certifications and lot differences are not covered. Confirm with both datasheets before replacing; ask us for samples or validation support.
Pre-replacement Checklist (NOR FLASH)
- Package & pinout compatibility (SOP8/WSON/SOIC8 pad map)
- SPI command set & Quad/QSPI support (Fast Read 0xEB, erase commands)
- Capacity, page size & sector architecture (256B page, 4K sector)
- Voltage range & speed grade (80/104/133MHz and quad-transfer rates)
- JEDEC ID & init flow (driver adaptation needed if ID differs)
- Write-protect, OTP & unique-ID security features
These are standard checkpoints for this product type. Verify each item and pilot-test before full switch-in. Ask us for samples, a replacement assessment report or FAE support - free samples and validation assistance provided.
