New microcontrollers from STMicroelectronics expand STM32U5 series, raising performance and energy efficiency for IoT and embedded applications

STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, has expanded its STM32 family of advanced microcontrollers (MCUs) with extra STM32U5 devices that raise performance while squeezing power consumption for longer runtimes and energy efficiency. The STM32U5 has also received NIST embedded random-number entropy source certification ; the industry’s first to receive this endorsement. The new MCUs extend the range of code and data storage to 128Kbyte Flash for cost-sensitive applications, while also adding high-density versions for complex applications and sophisticated smartphone-like user interfaces. Among these, the STM32U59x/5Ax with 4Mbyte Flash and 2.5Mbyte SRAM has the largest on-chip memory of any STM32 MCU to date. With their increased capabilities, the new MCUs enhance deeply embedded applications like environmental sensors, industrial actuators, building automation, smart appliances, wearable devices, eMobility controls, and others, especially in remote, difficult to access locations. As billions of such devices are being deployed worldwide for smart living and working, ST’s new MCUs accelerate progress by boosting performance, enhancing energy efficiency, and strengthening cybersecurity. All STM32 MCUs are based on industry-standard Arm Cortex-M embedded CPU cores and benefit from the powerful and...
