Microcontroller and accessories access ARM Cortex-M7 embedded design
Two STM32F7 microcontroller lines, accessories and options to the development ecosystem, ease access to embedded design based on the ARM Cortex-M7 core, says STMicroelectronics.
The STM32F722 and STM32F723 microcontrollers reduce memory footprint by integrating code-execution protection and high-speed USB PHY circuitry to streamline the development of connected applications.
The new variants have extra cryptographic features on-chip, such as an efficient AES256 HW engine. Package options range from a 64pin LQFP to 176pin LQFP or UFBGA for projects demanding high I/O count, and 256kbyte or 512kbyte of on-chip Flash memory with 256kbyte RAM.
Pin, package, and software compatibility between the new devices and STM32F7 variants with 256kbyte to 2Mbyte flash memory and 256 to 512kbyte RAM in packages up to 216pin TFBGA simplifies scaling. The microcontrollers can be ported throughout the STM32 family, which contains over 700 devices that cover all 32bit Cortex-M cores, with a range of peripheral, pin-count, and memory options.
A Discovery Kit, based on the STM32F769, with expansion connectors includes an eight-pin socket for Wi-Fi modules. It supports PoE and includes a 512Mbit Quad-SPI (QSPI) flash interface and accessories that to extend application reach, including the B-LCDAD-RPI1 15-pin single row Flexible Printed Circuit DSI adapter board and B-LCDAD-HDMI1 DSI-to-HDMI adapter, to attach a 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.
