The core runs at up to 168 MHz, which puts it in the tier for real-time motor control, digital power conversion, and audio processing where you need the MAC throughput without moving to a dedicated DSP or FPGA. The 1 MB of on-chip Flash and 192 KB of SRAM are sized for a single firmware image with room for an RTOS, a TCP/IP stack, and a moderate data buffer — no external memory needed for many closed-loop applications.
Industrial temperature range and peripheral complement
The 82 GPIOs break out through a 100-pin LQFP package, giving enough pins for a parallel LCD interface or an external bus (EBI/EMI) alongside CAN, multiple UARTs, SPI, I²C, and USB OTG.
ST lists this device as Active in its current portfolio. The base product number STM32F405 covers a family of density and package variants, so a pin-compatible drop-in within the same 100-pin LQFP footprint (the STM32F405RG or STM32F407VG, for instance) is possible if you later need more RAM or a different peripheral set — but the evidence here confirms the VGT6V is the active, shipping order code.
