The STM32F722RET6 powers Betaflight "F7" class flight controllers — a significant leap from the F4 generation. Running at 216 MHz with a Cortex-M7 core and hardware D-cache, it handles high-frequency gyro loops (8kHz+), bidirectional DSHOT, RPM filtering and complex OSD rendering simultaneously. Found in boards like Kakute F7, Matek F722, and SpeedyBee F7.
