### Supply Chain Context
A Findchips sourcing guide. Overview Evaluating STM32 alternatives was once a practice adopted only during times of shortage. However, seeking second sources to STMicroelectronics’ ubiquitous 32-bit ARM Cortex-M based microcontroller family has now become a standard design practice, regardless of current availability conditions. Teams building anything with a service life longer than a couple of years are now expected to name a backup part during the schematic review phase. Supplyframe’s demand
