Mass-Production and Identification Checklist

  1. Verify the full controller marking, suffix, PCB revision, and interface.
  2. Read the Flash ID from every channel and CE, then cross-check the compatibility table.
  3. Select a tool version containing the matching Flash database and firmware branch.
  4. Mass production destroys data; do not write firmware or run production when recovery is required.

Data Sources

Compatibility and benchmark figures come from the FlashInfo snapshot included with this site. Vendor and interface values are model-family inferences and do not replace manufacturer datasheets.
