Months ago I already stocked up on several models of 32bit microcontrollers to be able to work during the next few months, given the shortage, which seems to continue in 2022, and it is not known if also in 2023.
Right now there is practically nothing in stock at the usual suppliers. I managed to buy, at the time, quite a few microcontrollers from NXP and ST, mainly RT1024, RT1064, RT1166, RT1171, RT1172, STM32H747 and STM32H757. I also bought quite a few CAN bus FD controllers and some I2S sound amplifiers.
I recently tried to buy the RT1062s that Teensy4 uses, but someone beat me to it and bought them all, I think a little over 1000 units, I also tried a couple of hundred RT1166s that were put up for sale, but still someone bought all the next day.
I was reviewing the suppliers' stocks, to see what is in 32 bit, and I see that there are many NXP LPCs. What happens with these microcontrollers, why does nobody want them? There are references in general that remain unsold, I suppose because they are BGA with a very fine pitch of 0.65mm or less, but there are quite a few LPC references with a pitch of 0.8mm.
I have never used LPCs, but if necessary due to the lack of other microcontrollers, I could use them. Now I have quite a lot of other microcontrollers that I already bought months ago, but we don't know how long the shortage of components will last, it is said that 2022 will continue the same, and it is not known if also 2023.
