STM32U5 MCUs Meet Performance, Energy Efficiency, and Cybersecurity Requirements

STMicroelectronics (ST) has unveiled a new MCU that meets performance, energy efficiency, and cybersecurity requirements.

ST announced on the 6th that it has expanded its STM32 MCU family with the launch of the new STM32U5 device.

The STM32U5 delivers high performance while delivering lower power consumption for longer runtimes and energy efficiency, and is the industry's first to be certified as a NIST embedded Random-Number Entropy Source.

The new MCUs extend code and data storage to 128Kbytes of flash memory for cost-sensitive applications, while also adding high-density versions for complex applications and sophisticated user interfaces like smartphones.

Among them, the STM32U59x/5Ax has the largest on-chip memory among currently available STM32 MCUs, with 4Mbyte flash and 2.5Mbyte SRAM.

Enhanced capabilities can enhance the performance of highly embedded applications such as environmental sensors, industrial actuators, building automation, smart appliances, wearable devices, and electric mobility control, as well as remote applications that are particularly difficult to access.

Smart As billions of these devices are deployed globally for living and working smart, ST's new MCUs help improve performance and energy efficiency, as well as cybersecurity.

All STM32 MCUs feature industry-standard Arm® Cortex®-M embedded CPU cores and come with the powerful, easy-to-use STM32Cube and STM32Cube.AI development ecosystem.

The ecosystem integrates tools and software that can support customers' projects from start to finish, including converting pre-trained neural networks into optimized code to create cutting-edge AI/ML solutions.

The STM32U5 series leverages the latest Cortex-M33 core to further improve performance and energy efficiency, and enhance security against online and hardware attacks.

ST has added its expertise in ultra-low-power MCUs to this core and implemented the architecture by leveraging Arm's established principles for superior cybersecurity.

Some devices in this series also offer 2.5D graphics accelerators.

This creates a groundbreaking MCU series that offers a wide range of pin-to-pin and software-compatible products to support next-generation applications.

“As more and more applications demand longer runtimes from smaller batteries or energy harvesting, along with additional features, richer graphics, and faster performance, ST has developed and expanded the STM32U5 series to support them,” said Ricardo De Sa Earp, Executive Vice President of ST’s General-Purpose Microcontroller Subgroup. “These MCUs feature the latest Arm cores, unique ultra-low-power technologies, and generous on-chip memory, delivering a user-friendly experience.“ST’s NeoChrom graphics option is also available to enhance the enemy experience,” he said.

Ajax Systems, a key customer for ST's STM32U5 series, is already designing next-generation advanced wireless security and smart home solutions using the new MCUs.

“The STM32U5 series delivers the same performance as other MCUs with integrated DSP and floating-point coprocessor while significantly reducing power consumption,” said Max Melnyk, R&D director of the Ajax Devices business unit. “We are confident that ST’s solutions will be a key driving force in the development of our next generation of Ajax products.”
