32-Bit STM32 F7 Series MCU with ARM® Cortex&#

STMicroelectronics' STM32 F7 series MCU features an ARM Cortex-M7 core, operates at frequencies up to 200 MHz, and uses a 6-stage superscalar pipeline and floating point unit (FPU) to produce up to 1000 CoreMarks. Architectural innovations surrounding the MCU boost performance and ease of use. STMicroelectronics has included two independent mechanisms to reach zero-wait-state performance from both internal and external memories; their adaptive real-time (ART) accelerator for internal embedded Flash and L1 cache for both execution and data access from internal and external memories.

STM32F7 Ecosystem:
The STM32F722 and STM32F723 microcontrollers extend the offering of the STM32F7 family with code-execution protection and high-speed USB physical-layer (PHY) circuitry. These high-performance MCUs provide versatile package options such as 256 KB or 512 KB of on-chip Flash memory with 256 KB RAM and 64-pin LQFP up to 176-pin LQFP or UFBGA.

Features
  • 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 interface, and the Chrom-ART graphic accelerator
  • Peripheral speed independent from CPU speed (dual clock support), allowing system clock changes without any impact on peripheral operations
  • Even more peripherals, such as two serial audio interfaces (SAI) with SPDIF output support, three I2S half-duplex with SPDIF input support, and two USB OTG with dedicated power supply and dual-mode QuadSPI Flash
  • Large SRAM with a scattered architecture
    • 320 Kbytes of universal data memory, including 64 Kbytes of Tightly-Coupled Memory for Data (DTCM) for time critical data handling
    • 16 Kbytes of Tightly-Coupled Memory for Instructions (ITCM) for time-critical routines
    • 4 Kbytes of backup SRAM to keep data in the lowest power modes
Power efficiency Compatibility
  • 7 CoreMark / mW at 1.8 V
  • 00 µA typical current consumption in Stop mode with all context and SRAM saved
  • Cortex-M7 is backwards compatible with the Cortex-M4 instruction set
  • STM32F7 series is pin-to-pin compatible with the STM32F4 series
