The STM32F745VGT6 features an ARM Cortex-M7 core at up to 216 MHz with double-precision FPU (DP-FPU), offering approximately 3× the computational throughput of the F405. With 1MB Flash, 320KB SRAM (including 64KB tightly-coupled memory for latency-critical tasks), and LQFP-100 pinout, it is the performance choice for advanced flight control systems.
In the drone industry, the F745 is used as the "F7" Betaflight target, enabling 32kHz gyro sampling and high-frequency PID loops. It's also selected for industrial autopilot boards requiring Ethernet connectivity, multiple CAN buses, and generous UART ports for peripheral management.
