This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
STMICROELECTRONICS STM32 L5 Ultra-Low-Power MCUs
STMicroelectronics STM32 L5 Ultra-Low-Power MCUs offer flexible power control and enhanced security features for embedded applications that require high performance and low power consumption.
STM32 L5 MCUs are based on an Arm Cortex-M33 core with FPU that operates at up to 110MHz with embedded high-speed memories and an external memory controller, as well as an ST ART Accelerator for enhanced security. The MCU features Arm TrustZone technology and ST security technology, providing hardware-based security functions and securable I/Os, memories, and peripherals. = The MCUs employ ST’s FlexPowerControl and have integrated power conversion, providing flexible power management and reducing overall power consumption.
This includes low-power states with consumption as low as 17nA and operation as low as 62µA/MHz.
