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 (PSRAM)
- Interface mode (CR / legacy SRAM timing)
- Controller refresh support
- Density & width
- Standby & refresh current
- Package compatibility
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.
