STM32 F7 series of very high performance MCUs with ARM® Cortex®-M7 core

The STM32 F7 devices are the world’s first ARM® Cortex-M7® based 32-bit microcontrollers, setting the benchmark in performance.

Taking advantage of ST’s ART Accelerator™ as well as an L1 cache, the STM32 F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external Memory:  1000 CoreMark/428 DMIPS at 200 MHz fCPU.

Smart architecture with new peripheral set:

The STM32 F7 series unleashes the new Cortex M7 core:

• AXI and multi-AHB bus matrix for interconnecting Core, peripherals and memories
• Two general purpose DMA controllers and dedicated DMAs for Ethernet, high-speed USB On-The-Go and the Chrom-ART graphic accelerator.
• Peripheral speed independent from CPU speed (dual clock support) allowing system clock changes without impacting the function of the peripherals
• Even more peripherals, such as two serial audio interfaces (SAI) with SPDIF output support, three I2S half-duplex with SPDIF input support,  two USB OTG with dedicated power supply and Dual Quad SPI interface
• 320KBytes of SRAM with scattered architecture:
  

• 240 Kbytes of universal data memory
• a 16 Kbytes partition for sharing data over the bus matrix
• 64 Kbytes of Tightly-Coupled Data Memory (DTCM) for time critical data handling (stack, heap...)
• 16 Kbytes of Tightly-Coupled Instruction Memory (ITCM) for time critical routines
• 4 Kbytes of backup SRAM to keep data in the lowest power modes.
  

Power efficiency:

• 7 CoreMark/mW at 1.8V and 180 MHz
• 120µA typical current consumption in Stop mode with all context and SRAM saved
  

Compatibility:

• Cortex M7 is backward compatible with Cortex M4 instruction set
• STM32 F7 series is pin-to-pin compatible to the STM32 F4 series
