Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current selection guide to ensure correct package type and temperature rating. Confirm that the Low Density designation matches the required peripheral count, as some features like EBI are restricted to specific packages or densities. Cross-reference the datasheet revision date with your design timeline to account for any electrical characteristic updates.

Microcontrollers Selection Notes

Select this component when a balance of moderate program storage and extensive connectivity is needed within a compact footprint. The Low Density variant offers reduced pin counts compared to Medium Density parts while retaining essential peripherals like RTC and ADC. Ensure the application does not require USB or CAN interfaces, which are absent in the NUC100 series but available in higher-tier models.

Microcontrollers Part Context

This part belongs to the NuMicro NUC100 Advanced Line, designed for cost-sensitive applications demanding 32-bit performance comparable to traditional 8-bit controllers. The series targets industrial and consumer markets where reliable operation across wide voltage and temperature ranges is critical. It serves as a foundational MCU for embedded systems prioritizing serial communication and basic analog processing.

Microcontrollers Replacement Considerations

NUC100LC1BN: Offers identical functionality with 32 KB Flash instead of 64 KB.
