Engineering review checklist

  • Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
  • Check package pinout, boot configuration, programming interface and silicon-revision errata.
  • Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
