STMicroelectronics

 

STMicroelectronics has extended its STM32H7 family of MCUs to include new, high-performance dual-core devices which offer valuable power-saving features and enhanced cyber protection.

The STM32H7 series now includes dual-core microcontrollers with Arm® Cortex® -M7 and Cortex® -M4 cores able to run at up to 480MHz and 240MHz respectively. The existing single- core Cortex® -M7 STM32H7 parts also benefit from the increase in frequency to 480MHz. Dual- core STM32H7 microcontrollers are available with an embedded switching power supply for improved dynamic power efficiency.

The STM32H7 devices that include an integrated cryptography/hash processor, the STM32H755, STM32H757 and STM32H750, are particularly well suited to use in applications that require advanced authentication and encryption functions. These MCUs come with pre-installed keys and native secure services including Secure Firmware Install (SFI). SFI lets customers order standard products anywhere in the world and have the encrypted firmware delivered to an external programming company without exposing unencrypted code. In addition, built-in support for Secure Boot and Secure Firmware Update protects over-the-air feature upgrades and patches

The new STM32H7 parts’ outstanding performance draws on more than the new high-frequency version of the Cortex-M7 core. ST’s smart architecture, an efficient L1 cache and adaptive real-time ART Accelerator engine help the MCUs to set new speed records of 1,327 DMIPS and a 3,224 CoreMark score when executing from embedded Flash.

To maximize energy efficiency, each core operates in its own power domain and can be turned off individually when not needed.

Developers can easily upgrade existing applications through flexible use of the two cores. They can add a sophisticated user interface to an application such as a motor drive formerly hosted on a single-core Cortex-M4 MCU by migrating legacy code to the STM32H7 Cortex-M4 with the new GUI running on the Cortex-M7. Another example is to boost application performance by offloading intensive workloads such as neural networks, checksums, DSP filtering or audio codecs.
