STMicroelectronics has announced new STM32Cube software packs and tools, along with evaluation boards, to accelerate development with the latest STM32U5 microcontrollers (MCUs) that deliver superior feature integration, memory density, dynamic power consumption, and standby power and include a Low Power Background Autonomous Mode that lets direct memory access and key peripherals operate without CPU intervention.
The 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 smart watches, 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.
The STM32CubeU5 enablement ecosystem for STM32U5 provides software to help exercise MCU features like LPBAM, Wi-Fi, and Bluetooth Low-Energy (BLE) and Support for OpenBootloader eases implementation of custom bootloader code. Azure RTOS with ThreadX RTOS along with FreeRTOS and CMSIS OS wrappers ensures high performance and eases industry certifications. Moreover, 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.
The full-featured STM32U575I-EV evaluation kit is now available for $348 and STM32U5 MCUs with pricing start at $3.60 are now available in various packages including a 4.2mm x 3.95mm WLCSP and 7mm x 7mm UQFN48 and UFBGA169.
