New Series of MCUs Increase IoT Processing Performance and Security for IoT Devices
STMicroelectronics (STMicroelectronics, STMicroelectronics, STMicroelectronics introduced a new series of further enhancements STM32H7 new series of microcontrollers (MCU). The new series features built-in SRAM (1MB), up to 2MB of flash memory, and a rich variety of communication peripherals, further paving the way for the proliferation of smart devices. STMicroelectronics advanced research and development of advanced 40nm chip manufacturing technology, combined with product architecture innovation, so that a substantial increase in the operational performance of the new series of products, play the processor core optimization performance, the system within the ultra-high-speed data transmission mode of operation, low power consumption At 280uA / MHz, standby power consumption is less than 7uA. The working power consumption is reduced by half compared with the previous generation product. The new lineup, the STM32H743, is based on the 400MHz ARM Cortex-M7 core and is ideal for industrial gateways, home automation, telecom equipment and smart consumer electronics, as well as high performance motor control, home appliances and rich user interface features Small appliances. The new product also incorporates advanced security features, including cryptographic algorithms accelerator and secure key storage, ensuring IoT hardware data security and preventing network threats at the factory and in the field, making it ideal for IoT hardware developers . Following the STM32F7 family of ARM Cortex-M7 processor cores, the STM32H7 family is the first Cortex-M7 microcontroller to feature 40nm flash memory manufacturing technology and is the first microcontroller to operate at 400MHz. These significant advances have allowed the STM32H743 to record the 856DMIPS 1 Computational Performance Test and score a 2010 high on the EEMBC CoreMark test. STMicroelectronics' 40nm process dramatically increases storage capacity, allowing the STM32H743 to combine 2MB of dual-zone flash memory with 1MB of SRAM bulk memory. STMicroelectronics unique level of cache and TCM memory, STM32H743 internal and external memory interaction efficiency, developers are no longer subject to memory resources, you can freely develop more sophisticated, feature-rich applications. This new product saves more development time and effort than previously designated features with extremely limited resources. Next-generation STM32 chip peripheral device features. As the first product in the new series, the STM32H743 brings together 35 communications perimeters and supports advanced communication protocols and CAN FD, SDCARD (4.1), SDIO (4.0) and MMC (5.0) standards as well as 11 enhanced analog functions Including a low-power 14-bit A / D converter ADC, a 12-bit A / D converter DAC and op amp with sampling rates up to 2Msample / s and 22 timers, including a high-resolution 400MHz timer. The STM32H7 family of microcontrollers also incorporates STM32 Dynamic Efficiency energy-saving technology to reduce operating power by half over the previous generation STM32H7. STMicroelectronics has also developed several storage areas that support dynamic performance power management. D1, D2, and D3 are used to process intensive tasks as well as external perimeter (D1 area) interconnected by a high-performance AXI bus matrix, communication link tasks (D2 area), and energy efficient batch processing mode D3 area). To maximize energy efficiency, each power-loss area can be independently switched. When closed, the programmable design event can be restarted. While improving the external perimeter, STMicroelectronics retains the system-wide convenience brought by market acceptance and compatibility of different series. STM32F4 and F7 series of products in the pin, the outer periphery and the software is fully compatible. Mutual compatibility greatly simplifies application expansion designs, re-using design experiences accumulated in the past and previously developed code for multiple development projects. STMicroelectronics STM32H7 family of Cortex-M7 microcontrollers already have a very mature supporting design system, including STM32H7 series of special evaluation board, Nucleo development board and exploration kit, STM32Cube embedded software development platform will support ARM mbed Os operating platform, through ARM for all developers to provide advanced software stack development and application. From the LQFP100 to the TFBGA240, the new products will be available in 6 packages and available immediately. STM32H743VGT6 built-in 1MB flash memory and 1MB SRAM, which uses 100-pin LQPF100 package. STM32H743 and STM32H7 follow-up production line will be the second quarter of 2017 production.
