Подскажите какой из чипов STM32 на сегодня получается самый дешевый и доставаемый (массовый). Например sam7s64 зачастую получатся дешевле чем sam7s32 только за счет того что из поставщики закупают большими партиями.

Не самые доставаемые на сегодняшний момент, но, наверное, самыми дешевыми будут недавно выпущенные Low-desity access line STM32F101x4/6 и Low-desity USB access line STM32F102x4/6 c флешем 16 и 32кб. Похоже, что с их выпуском 32-битники будут использовать где попало.
