STMicroelectronics has released entry-level, mid-range, and high-end development boards for the latest members of its STM32F7 microcontroller series , which are now entering volume production with up to 2Mbyte of on-chip Flash memory and peripherals that help create rich user interfaces.
Providing timely support for design starts, the new development tools include a low-cost STM32 Nucleo-144 board featuring the STM32F767 variant. Also available is a Discovery Kit supporting the STM32F769, which has TFT-LCD and MIPI®-DSI support. In addition, there are highly featured evaluation boards for the STM32F769 and the STM32F779, which has a cryptographic accelerator for security-conscious applications. The evaluation boards and Discovery Kit also come with a 4-inch QWVGA 800×400 MIPI-DSI display featuring a capacitive touchscreen.
The STM32F7 ecosystem enables developers to create microcontroller applications with sophisticated user interfaces that formerly required the resources of a Microprocessor Unit (MPU). The MCU devices, which are based on the 216MHz/462DMIPS/1082 CoreMark® ARM® Cortex®-M7 core with double-precision floating-point unit and DSP instructions, combine enhanced graphics capabilities with extensive connectivity through:
- ST’s Chrom-ART Accelerator™ and a hardware JPEG accelerator for high-speed graphics rendering;
- Support for TouchGFX, which allows high-performance graphics and touch at minimal CPU loading;
- Support for Embedded Wizard, which allows high-performance graphics and comes with a PC-based utility that helps build GUIs using graphical tools and drag & drop actions;
- STemWin professional graphics library and development tools;
- Support for USB2.0 with OTG;
- CAN2.0 port and Ethernet with IEEE 1588 time-stamping ideal for industrial applications;
- HDMI Consumer-Electronics Control (CEC), a camera interface, and dual-mode Quad-SPI interface to high-speed off-chip memory;
- Multiple 16- and 32-bit timers and 12-bit 2MSPS ADCs;
- Audio features including 12-bit DACs, I2S (Inter-IC Sound) serial interface with Phase-Locked Loop (PLL) support, digital filters for a sigma-delta modulator, and an S/PDIF receiver.
The STM32F769I-EVAL and STM32F779I-EVAL evaluation boards are priced at $360, while the $79 Discovery Kit (STM32F769I-DISCO) and the $23 STM32 Nucleo-144 board (NUCLEO-F767ZI) enable extremely low-cost design starts. All are available immediately, and can be ordered directly from ST or distributors.
