The evidence carries a lifecycle stage of 'eol_hot' alongside an 'Active' product status. This unresolved flag means a sourcing buyer must verify current factory support.
Within the STM32F439 series, the STM32F439VIT6 is the same die in a 100-lead LQFP with fewer I/O. For a full 208-lead pin-compatible replacement, the STM32F439NI (176-lead) or STM32F439AI (176-lead) share the core but differ in package and I/O count — verify the specific pinout against your layout.
The operating temperature range is -40°C to 85°C, suitable for industrial and outdoor telecom environments.
The core runs at 180 MHz, giving it DSP-class headroom for real-time control loops and audio processing.
