Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Digi International channels or certified distributors. Confirm the specific suffix indicates the 125 MHz speed grade and commercial temperature range. Check for RoHS compliance documentation and ensure the BGA-388 package matches design requirements. Validate that the part status aligns with long-term availability needs.

Application Specific Microcontrollers Selection Notes

Select this model when a 125 MHz processing speed is sufficient for the application. Ensure the design accommodates the BGA-388 footprint and 3.3V I/O logic levels. Verify that the commercial temperature range (0°C to +70°C) meets environmental constraints. Consider the integrated peripherals like Ethernet and PCI if external controllers are to be avoided.
