STM32 Microcontroller Enhancements
STM delivers Record Performance and Advanced Secure Services for IoT
STMicroelectronics is paving the way to intelligent smart devices with its record-breaking STM32H7 series of microcontrollers , which embeds the highest SRAM memory ( 1Mbytes ), Flash memory up to 2MB , and the richest connectivity peripheral set ever seen in the STM32 platform .
“ The diversity of IoT and embedded applications demands scalable MCU solutions ,” said James McNiven , general manager for CPU and media processing groups , ARM . “ The advanced capabilities of the H7 series will enable developers to address the high end of the embedded market while delivering all of the efficiency and ease-of-use benefits of an ARM Cortex-M based device . With the ARM mbed OS technology supported on the Cortex-M7 , developers can have easy access to advanced software stacks for fast development .”
Michel Buffa , General Manager , Microcontroller Division , STMicroelectronics , added , “ In addition to its industry-leading execution performance , the STM32H7 series also significantly increases on-chip resources while realizing power savings that are vital for future generations of embedded systems and offering top-notch protection from threats and intrusions . The dramatically increased memory density , in particular , eliminates traditional constraints on developers and so accelerates time to market for exciting new products .”
Technical information :
The STM32H7 series features the ARM Cortex-M7 core that also powers the STM32F7 series . The new STM32H7 series is the industry ’ s first Cortex-M7 fabricated on the advanced 40nm Flash process and the first to run at 400MHz . These important enhancements enable the STM32H743 to set new performance records of 856DMIPS and an EEMBC CoreMark score of 2010 .
ST ’ s 40nm geometry is a key factor enabling the leap in memory density , as it allows the STM32H743 to integrate 2MB of dualbank Flash with a huge 1MB SRAM that frees developers from the resource constraints that typically complicate high-end
Central to this leap in capability is ST ’ s own highly advanced 40nm chip-fabrication process combined with innovations in the product architecture , unleashing the performance of the core and enabling ultra-fast data transfers through the system while consuming less than 280uA / MHZ in run mode and less than 7uA in stand-by . The first device in the new series is the STM32H743 , which features the ARM Cortex-M7 core running at 400MHz . This MCU is the highest-performing implementation of ARM ’ s highestperforming Cortex-M core currently in the market . The STM32H7 microcontrollers are perfect for industrial gateways , home automation , telecom equipment and smart consumer products , as well as high-performance motor controls , domestic appliances , and small devices with rich user interfaces . Integrated state-of- the-art security features , including cryptographic accelerators and provision for secure-key storage , provide connected objects with a high level of protection against online threats both during the manufacturing and in the field ; perfect for Internet of Things ( IoT ) appliances . embedded development . The STM32H743 interacts efficiently with either internal or external memory , thanks to its unique L1 cache and TCM memory . These freedoms allow applications to become more sophisticated and feature-rich , while also saving the engineering time and effort traditionally needed to implement the specified functionality within extremely limited resources . With the launch of the STM32H7 series , ST is also introducing a new generation of STM32 on-chip peripheral functions . The first device in the new series , the STM32H743 , draws on a pool of 35 communication peripherals that support advanced protocols and standards such as CAN FD , SDCARD ( 4.1 ), SDIO ( 4.0 ), and MMC ( 5.0 ). There are also 11 enhanced analog functions including low-power 14-bit ADCs running at up to 2Msample / s , 12-bit DACs and op-amps , as well as 22 timers , which include a high-resolution timer running at 400MHz .
As well as dramatically increasing the performance and resources , the STM32H7 MCU series also incorporates STM32 Dynamic Efficiency energy-saving techniques that help the new devices consume half the dynamic power of their predecessors in the STM32F7 series . Central to this leap in energy efficiency is ST ’ s own highly advanced 40nm chip-fabrication process that , in combination with innovations in the Company ’ s Dynamic Efficiency technologies , allows precise optimization of power consumption . These optimizations include Dynamic Voltage Scaling that adjusts power consumption according to performance demands , and Batch-Acquisition Mode that captures data directly into memory without waking the core from energy-saving mode . ST has also created multiple memory domains that support Dynamic Efficiency energy management . D1 , D2 , and D3 domains are dedicated respectively to processing- intensive tasks and peripherals interconnected through a high- performance AXI bus matrix ( D1 domain ) as well as connectivity tasks ( D2 domain ), and the energy-saving Batch Acquisition Mode ( D3 domain ). Each domain can be powered on or off independently to maximize energy savings , and can be reactivated by programmable events .
