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

Availabilty: Series production in Q2/2015.
