- Revision History
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.
