ST’s New Enhanced STM32 MCus Logs Record Performance and Advanced Secure Services for IoT

STM32H7 series

STMicroelectronics new STM32H7 series of microcontrollers is claimed to pave way to even more intelligent smart devices everywhere. The new devices are touted to embed the highest SRAM memory (1Mbytes), Flash memory up to 2MB, and the richest connectivity peripheral set ever seen in the STM32 platform.

Powering the core is ST’s own highly advanced 40nm chip-fabrication process combined with innovations in the product architecture 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 features:

  • The ARM Cortex-M7 core running at 400MHz.
  • This MCU is the highest-performing implementation of ARM’s highest-performing 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.

“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.”

Additional Specs Include

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.

Availability, Pricing and Packaging

Six packages ranging from LQFP100 to TFBGA240 are sampling now. The STM32H743VGT6 with 1MB Flash and 1MB SRAM in a 100-pin LQPF100 package starts at budgetary pricing of $8.17 for orders of 10,000 pieces.

The STM32H743 and further STM32H7 product lines will be in full production in Q2 2017.
