STMicroelectronics has introduced new STM32F7 microcontroller lines and added accessories and options to the development ecosystem, easing access to high-performance embedded design based on the ARM Cortex -M7 core.
The latest STM32F722 and STM32F723 microcontrollers (MCU) in the very high-performance STM32F7 series reduce memory footprint by integrating value-added features including code execution protection and high-speed USB physical layer (PHY) circuitry that streamline development of connected applications. The STM32F732 and STM32F733 variants come with extra cryptographic features on-chip, such as an efficient AES256 HW engine. There are versatile package options from a 64-pin LQFP up to 176-pin LQFP or UFBGA for projects demanding high I/O count, and 256 KB or 512 KB of on-chip Flash memory with 256 KB RAM.
Extensive pin, package and software compatibility between the new devices and higher-end STM32F7 variants with 256 KB to 2 MB Flash memory and 256 KB to 51 2KB RAM in packages up to 216-pin TFBGA simplifies design scaling for product differentiation and future-proofing. STM32F7 projects can also be readily ported throughout the large STM32 microcontroller family, which contains over 700 devices that cover all 32-bit Cortex-M cores and offer a wide range of peripheral, pin count and memory options.
ST is also introducing a new Discovery Kit, based on the STM32F769, with expansion connectors that include an 8-pin socket for Wi-Fi modules. The kit supports Power over Ethernet (PoE). Other features include a 512 Mbit Quad-SPI (QSPI) Flash interface and new accessories that enhance flexibility and extend application reach, including the B-LCDAD-RPI1 15-pin single row flexible printed circuit DSI adaptor board and B-LCDAD-HDMI1 DSI-to-HDMI adaptor, which enhance flexibility to attach a wide variety of displays. The kit can also be supplied with the B-LCD40-DSI 4-inch WVGA capacitive touchscreen display pre-fitted, or without the display for extra affordability. The B-LCD40-DSI can be ordered separately if needed to upgrade the kit at a later date.
