STMicroelectronics has begun producing microcontrollers with the new ARM Cortex-M7 processor, which is the newest Cortex-M core for advanced consumer, industrial, and Internet-of-Things (IoT) devices. The new STM32F7 microcontrollers combine the Cortex-M7 core with advanced peripherals.
The STM32F7 Discovery Kit includes the STM32Cube firmware library along with support from software-development tool partners and the ARM mbed online community. The $49 Discovery Kit includes a WQVGA touchscreen color display, stereo audio, multi-sensor support, security, and high-speed connectivity. In addition to an integrated ST-Link debugger/programmer (you don’t need a separate probe), you get unlimited expansion capability via the Arduino Uno connectivity support and immediate access to a wide variety of specialized add-on boards.
STM32F7 devices are available in a range of package options from a 14 mm × 14 mm LQFP100 to 28 mm × 28 mm LQFP208, plus 10 mm × 10 mm 0.65-mm-pitch UFBGA176, 13 mm × 13 mm 0.8 mm-pitch TFBGA216, and 5.9 mm × 4.6 mm WLCSP143. Prices start at $6.73 for the STM32F745VE in 100-pin LQFP with 512-KB on-chip flash memory (in 1,000-unit orders).
The STM32F7 development ecosystem includes both the Discovery Kit and two evaluation boards (STM32746G-EVAL2 and STM32756G-EVAL2) that cost $560 each. The STM32F7 Discovery Kit (STM32F746G-DISCO) gives full flexibility to fine-tune hardware and software at any time. You also benefit from the associated STM32CubeF7 firmware, and the ability to re-use all STM32F4 software assets due to code compatibility.
