Mean time between failure (MTBF) and Failures in time (FIT) respectively indicates the average time a product can function before failing, and the anticipated failure rate of a product during its lifetime.
We regularly receive requests regarding this information on the ST Community, (especially STM32) but these requests must be handled directly through our Online Support System.
To request the MTBF/FIT value on an STM32 or any given STMicroelectronics product, submit a new Online Support case at https://my.st.com/ols as shown below.
