Frequently asked questions
Does ST publish an official replacement or pin-compatible alternate for the STM32F439IIH6?
Check the STMicroelectronics product change notification and cross-reference guide for STM32F4 pin-compatible successors in the same 201-UFBGA package. The official cross-reference, if any, will be in the L* lifecycle data — an RFQ will surface it if one exists.
What are the supply voltage and temperature limits for this part?
1.8 V to 3.6 V on Vcc, with an operating ambient of -40°C to 85°C. The 3.3 V rail is the standard operating point for most industrial logic designs.
How much memory does this part carry?
2 MB of Flash and 256 KB of SRAM — the largest Flash variant in the STM32F4 lineup at time of introduction. Sufficient for RTOS plus a fieldbus stack without external memory in most industrial gateway and HMI designs.
