ST Presents STM32Cube Ecosystem for STM32U5 MCUs

As the first STM32 MCUs to leverage advanced 40nm process technology, the STM32U5 series delivers superior feature integration, memory density, dynamic power consumption, and standby power compared to alternative products in the market.

STMicroelectronics (ST) has launched new STM32Cube ecosystem including software packs and tools, as well as evaluation boards, to accelerate development with the latest STM32U5 microcontrollers (MCUs), which are now ready for mass-market applications with stock at authorized distributors.

ST Ecosystem MCUsThe STM32U575 and STM32U585 MCUs combine security and power-saving innovations with the increased performance and energy efficiency of the latest Arm® Cortex®-M33 core.

With up to 2MB of Flash memory on-chip, typical applications include smart, connected consumer products such as activity trackers and smartwatches, as well as smart-home equipment, utility meters, equipment for industrial sensing and signaling, mobile point-of-sale (POS) terminals, insulin pumps, and glucose meters.

As the first STM32 MCUs to leverage advanced 40nm process technology, the STM32U5 series delivers superior feature integration, memory density, dynamic power consumption, and standby power compared to alternative products in the market.

There are also new power-saving features including a Low Power Background Autonomous Mode (LPBAM) that lets direct memory access (DMA) and key peripherals operate without CPU intervention. With an updated ST ART Accelerator™, the ability to turn off unused MCU memory, and a selectable DC/DC converter and low-dropout (LDO) regulator combination, dynamic power is less than 19µA/MHz.

The STM32CubeU5 enablement ecosystem for STM32U5, available on ST.com and GitHub, has more than 200 project examples and provides software to help exercise MCU features like LPBAM, Wi-Fi®, and Bluetooth® Low-Energy (BLE).

In addition, the X-CUBE-STL self-test library and functional safety documentation assist safety-critical application development and accelerate IEC61508 SIL certification of STM32U5-based products.

There are also software packages that simplify cybersecurity and help comply with industry best practices. These include reference code for Secure Boot and Secure Firmware Update (SBSFU) and a Trusted Firmware (TF-M) example that leverages Arm’s TrustZone® isolation within the core to implement secure services for PSA level 3 and SESIP level 3 certifications.

ST’s industry-certified X-CUBE-CRYPTOLIB cryptographic library is updated with simplified API and extra cryptographic algorithms, and support for Secure Firmware Install (SFI) protects downloading of custom firmware.

These software packages work with the MCUs’ enhanced hardware security features, which include strengthened protection against side-channel attacks as well as internal monitoring to erase secret data, which meets payment-card industry (PCI) requirements for POS applications.
