What does your crystal ball say about which microcontroller manufacturers, product lines, and/or package types are likely to have the best availability over the next 1-2 years? Would you expect everything to be impacted by the global chip shortage more-or-less equally, or will some kinds of microcontrollers maintain better availability than others?
I'm redesigning a product that I hope will sell around 2000 units per year, and if there were no chip shortages I'd probably choose something like a SAMD21 or SAMD51, or a comparable STM32 device. But I'm also looking at xMEGA and AVR-Dx stuff. Availability of AVR-Dx right now seems better than the others, but I'm not sure if that will last. Right now it's hard to find ANY microcontrollers that are available in > 1000 unit quantity, with confidence that they'll still be available in 6 months, a year, two years. What's your best prediction for the future?
