The STM32F7x3 line offers the performance of the Cortex-M7 core (with floating point unit) running up to 216 MHz while reaching similar lower static power consumption (Stop mode) versus the STM32F427/429/437/439 lines.

  • Performance: At 216 MHz fCPU, the STM32F7x3 delivers 1082 CoreMark / 462 DMIPS performance executing from Flash memory, with 0-wait states thanks to ST’s ART Accelerator. The FPU and DSP instructions enlarge the range of addressable applications. External memory can be used with no performance penalty thanks to the L1 cache (I/D 8 Kbytes + 8 Kbytes).
  • Power efficiency: ST’s 90 nm process, ART Accelerator and dynamic power scaling enables the power consumption in Run mode and executing from Flash memory to be at 7 CoreMark / mW at 1.8 V. In Stop mode, power consumption is typically 100 µA.
  • Integration:
    • Audio: Two dedicated audio PLLs, three half-duplex I²S interfaces and a new serial audio interface (SAI) supporting time-division multiplex (TDM) mode.
      Up to 21 communication interfaces (including four USARTs in addition to four UARTs running at up to 12.5 Mbit/s, up to five SPIs running at up to 50 Mbit/s, three I²C interfaces with a new optional digital filter capability, one CAN, two SDIO, USB 2.0 full-speed device/host/OTG controller with an on-chip PHY and a USB 2.0 high-speed/full-speed device/host/OTG controller (with on-chip high-speed PHY).
    • Analog: Two 12-bit DACs, three 12-bit ADCs reaching 2.4 Msample/s or 7.2 Msample/s in Interleaved mode.
      Up to eighteen 16- and 32-bit timers running at up to 216 MHz.
      Easily extendable memory range using the flexible memory controller with 32-bit parallel interface, and supporting Compact Flash, SRAM, PSRAM, NOR, NAND and SDRAM memories or using the Dual-mode Quad-SPI Flash memory interface to allow code execution from external serial Flash memory.
      An analog true random number generator.

The STM32F7x3 line comes with the proprietary code Read-out-protection feature

The STM32F7x3 line provides variants from 256 to 512 Kbytes of Flash memory and up to 256 Kbytes of SRAM including up to 64 Kbytes of Tightly-Coupled Memory for Data (DTCM), 16 Kbytes of Tightly-Coupled Memory for Instructions (ITCM), and 4-Kbyte Backup RAM, in 100- to 176-pin packages.
