We’ve already seen Atmel started shipping its SAM V71 Xplained Board based on its latest Cortex M7 a few days ago, but Atmel is not the company which recently introduced a Cortex M7 development kit, as ST Micro also launched an STM32F7 Cortex M7 development kit with Arduino headers and 4.3″ LCD at the end of June.

STM32F7_Development_KitThe “Discovery Kit with STM32F746NG MCU” (STM32F746G-DISCO) comes with the following specifications:

  • MCU – STMicro STM32F746NGH6 Cortex M7 MCU with 1 MB Flash, 340 KB RAM, in BGA216 package
  • Memory – 128-Mbit (16 MB) SDRAM (64 Mbits accessible)
  • Storage – 16 MB Quad-SPI Flash memory, and micro SD slot
  • Display – 4.3″ 480×272 color LCD-TFT with capacitive touch screen
  • Camera – Camera connector
  • Connectivity – Ethernet connector compliant with IEEE-802.3-2002
  • USB
    • USB OTG HS with Micro-AB connectors,  USB OTG FS with Micro-AB connectors
    • USB functions: virtual COM port, mass storage, debug port
  • Audio – SAI audio codec, line IN and OUT jacks, stereo speaker outputs, 2x ST MEMS microphones, and S/PDIF RCA input connector
  • Debugging –  On-board ST-LINK/V2-1 supporting USB re-enumeration capability
  • Misc – 2x push buttons (user and reset)
  • Expansion Headers:
    • Arduino Uno V3 connectors
    • RF-EEPROM daughterboard connector
  • Power Supply
    • ST LINK/V2-1
    • 5V via USB FS connector or USB HS connector
    • VIN from Arduino connector
    • External 5 V from connector
    • Output for external applications: 3.3 V or 5 V
  • Dimensions – N/A

STM32F7-DISCOVERY_PinoutThe board supports various development toolchains such as IAR EWARM (IAR Embedded Workbench), Keil MDK-ARM, GCC-based IDEs (free AC6: SW4STM32, Atollic TrueSTUDIO,…), and ARM mbed online.  The company also released STM32CubeF7 embedded software for STM32F7 series which includes low level drivers, USB, TCP/IP, File system, RTOS, Graphic and more. You’ll need a Windows XP, 7, or 8 computer to use the board, because the drivers for ST-LINK/V2-1 are only available for Windows.

One developer got hold of the board and wrote a C program showing some of its graphics capabilities.

You can find more details, including the board’s user manual and hardware design files, as well as purchase the board on STM32F746G-DISCO product page.
