The value of a layered framework is portability: change the MCU and, once the HAL layer is adapted, the application code above it barely changes.
Faster development means MCU part numbers switch more often, which tends to increase the number of part numbers ordered in smaller quantities. Kewei Technology recommends favouring MCU families with mature ecosystems and complete documentation — long-term supply and support matter more than unit price.
Kewei's take: what this means for procurement
Progress like this usually means supply of the affected chips loosens gradually, though popular part numbers can stay tight in the short term. Build a list of your high-volume lines, compare prices regularly and order in batches.
