STM32F722/723 and crypto-enhanced STM32F732/733 microcontroller lines will enter volume production in Q1 2017. Pricing starts from $5.04 (for 10,000 units) for the STM32F722RET6 in LQFP64.

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 STM32F723microcontrollers 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 connectedapplications.TheSTM32F732 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 256KB or 512KB of on- chip Flash memory with 256KB RAM. Extensive pin, package, and software compatibility between the new devices and higher-end STM32F7 variants with 256KB to 2MB Flash memory and 256KB to 512KB 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 adapter board and B-LCDAD-HDMI1 DSI-to-HDMI adapter, 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. The STM32F769 Discovery Kits (starting from $49) with wireless-ready baseboards are available immediately, as are the DSI and HDMI display-adapter boards and the 4-inch WVGA MIPI-DSI touchscreen LCD.

Toshiba Introduces Single-Chip, Low Pin-Count MCUs for Control of Multiple Motors ARM® Cortex®-M devices realize efficient motor control and improved power factor Toshiba Electronics Europe has developed a new range of microcontrollers that allow a single-chip, with a low pin-count (32 to 64 pins), to control multiple motors. The MK4 group is the second offering in Toshiba’s TXZ™ family of high-speed, low power consumption microcontrollers that incorporate the ARM® Cortex®-M core. The new MCUs meet the need to reduce energy and save space in motor control applications ranging from home appliances such as washing machines and refrigerators to power tools, ventilation fans, electric bicycles and industrial motion control. Until now, driving two motors typically required an MCU[1] in a 100-pin type package. Toshiba’s 64-pin TXZ family products, however, can control two motors thanks to the ability to detect motor position via an integrated, high-speedAD converter with a 0.5μs conversion speed. The new devices are based on the ARM® Cortex®-M4F operating at up to 80MHz and incorporating a floating point processing unit. As well as the high-precision ADC, the devices feature high-speed Flash memory with 80MHz operation, a co-processor for Toshiba’s original vector engine, and 3-channel op-amps with selectable gain. Together, they ensure the new products realize efficient motor control while improving the power factor and system control. Devices in the TXZ family support the RAMScope
