Frequently asked questions
Does the STM32F446RET7TR support ECC on SRAM or lockstep dual-core operation for functional safety?
This SKU is a single-core ARM Cortex-M4 part; it does not feature lockstep core architecture. ECC on SRAM availability is a silicon variant and temperature-grade detail not confirmed in the available specs — buyers targeting IEC 61508 SIL-2 should verify the SRAM ECC status against the full datasheet and consider the STM32F4 Safety-qualified line for SIL-2 applications.
