Frequently asked questions
What is the closest pin-compatible alternative to STM32F446VET6?
There is no official pin-compatible second source at the same density and 100-LQFP package. The STM32F446ZET6 (144-LQFP) shares the same core and memory but requires a different PCB footprint. Verify fit before substituting.
What is STM32F446VET6's listed speed?
The core runs at 180 MHz, which is the maximum clock for the STM32F446 series ARM Cortex-M4 with FPU.
What compliance documentation does ST provide for STM32F446VET6?
STMicroelectronics provides RoHS, REACH, and conflict-minerals declarations for this part. UL and IEC certifications are not listed for this component; check the product change notification (PCN) for any compliance updates.
Where can I buy STM32F446VET6?
This part is sourced through independent distribution. It is quoted to order against an RFQ, with availability and current pricing confirmed at quote time.
