Memory and peripheral budget
The Flash is enough for a moderate application stack including a real-time OS, communication protocol libraries, and application code, while the 64 KB RAM handles typical data buffers and stack without external memory. The 86 I/O lines in the 100-LQFP package give ample room for parallel sensor interfaces, display buses, and control signals. For mixed-signal control applications, the ADC channel count supports multi-phase current sensing or multi-axis position feedback without external multiplexers.
STMicroelectronics lists the STM32F302VDT6TR as Active. No last-time-buy or end-of-life notification has been issued for this base product number. For production programs that require multi-year availability, this part carries no imminent obsolescence risk, and the STM32F3 series has broad second-source compatibility within the STM32 ecosystem.
