The new STM32 F7 microcontroller (MCU) series leverages the ARM Cortex-M7 core, just announced as ARM’s newest and most powerful Cortex-M processor. ST’s STM32 F7 series leapfrogs the industry’s previous high-performance 32-bit Cortex-M champ — ST’s own STM32 F4 — in delivering up to twice as much processing and DSP performance that is accessible via a seamless upgrade path.
