STM32F405VGT6

STM32F405VGT6 is a high-performance Arm Cortex-M4 microcontroller from STMicroelectronics with single-precision FPU and DSP instructions, running at 168 MHz with 1 MB Flash and 192+4 KB SRAM in a 100-pin LQFP package, with a 10-year longevity commitment on the ST product page. The Cortex-M4 with FPU and the ART Accelerator's 0-wait-state Flash execution are the selection points: motor-control math, digital filtering and floating-point algorithms run at the full 210 DMIPS throughput, which is why this part anchors flight controllers, industrial drives and audio processing. Selection advice: compared with STM32F407VGT6, the F405 omits the Ethernet MAC and parallel camera interface - if your design does not need network connectivity, the F405 delivers identical compute in the same LQFP-100 footprint at a lower position in the BOM. Match the full VGT6 ordering code (1 MB Flash, LQFP-100); firmware is qualified against a specific density.
