STMicroelectronics continues to enhance flexibility for developers working with high-performance STM32F722/723 microcontrollers. A new-generation Discovery kit provides access to the STM32F723’s unique high-speed USB PHY, and a new STM32 Nucleo-144 board supports the STM32F722. With rich on-board features including MEMS microphones and sensors, an audio codec, and a display for user-interface development, the STM32 Discovery kits are ready to support creative demonstrations.

Building on the high performance of the STM32F7, the new STM32F723E-DISCO heralds the next generation in flexibility by enabling developers to leverage a richer pool of modules from third-party vendors to further expand functionality.

In addition to Arduino Uno pin headers, it features a Pmod connector from Digilent and a newly defined STMod+ connector that lets users connect through a provided fan-out add-on board to a Wi-Fi module, SeedStudio Grove modules, MikroElektronika click boards, or to a breadboard for quick prototyping.

In addition, the Discovery board has a High-Speed USB connector to take advantage of the USB-HS (High-Speed) Device physical layer (PHY) integrated in the STM32F723IEK6 MCU, as well as USB-FS (Full-Speed) connector and a TFT 240x240-pixel LCD touchscreen. There are also preloaded demonstrations, including a WAV audio player, a simple video player, and a voice recorder.

ST has also introduced the NUCLEO-F722ZE board, which is ideal for prototyping and community use. As a STM32 Nucleo-144 board, it contains a 144-pin STM32F722ZET6 MCU featuring 512 Kbytes of Flash memory. It has an ST Zio connector that supports Arduino Uno V3 connectivity, as well as an ST morpho extension pin header giving access to all the MCU I/Os.

Support for ST-LINK/V2-1 simplifies programming and debugging without a separate probe. The board comes with the STM32 Cube Hardware Abstraction Library (HAL) and software examples.

Both boards are available immediately from distributors or from the ST website, priced $39 for the STM32F723E-DISCO and $19 for the NUCLEO-F722ZE.
