The STM32F7 series is one of our very high-performance MCUs. Taking advantage of ST’s ART Accelerator™ as well as an L1 cache, STM32F7 microcontrollers delivers the maximum theoretical performance of the Arm® Cortex®-M7 core, whether the code is executed from embedded Flash or external memory: 1082 CoreMark /462 DMIPS at 216 MHz fCPU.
