  • A second and third volt- age monitor circuit tracks the unregulated supply to provide a power fail warning or monitors different power supply voltage.
  • 2V 2 M O N V2 Voltage Monitor Input.
  • active until the V2MON drops below 1V (V2MON falling).
  • active until the V3MON drops below 1V (V3MON falling).
  • For example, if the present V TRIPx is 2.9 V and the new VTRIPx is 3.2 V, the new voltage can be stored directly into the V TRIPx cell.

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.
