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.
- 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 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
The 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.
Thanks to Nanik for the tip.
