April 19, 2024: STMicroelectronics, a prominent semiconductor provider catering to a wide array of electronics applications, has unveiled a cutting-edge lineup of energy-efficient and cost-effective microcontrollers (MCUs), poised to slash energy consumption by up to 50% compared to previous iterations. This breakthrough not only extends battery life, reducing the need for frequent replacements and minimizing environmental impact but also opens avenues for battery-free operation through energy-harvesting systems like photovoltaic cells.

In the global drive towards sustainability, smart buildings and Internet of Things (IoT) solutions play a pivotal role in optimizing energy usage and resource management. At the core of these systems lie ST's microcontrollers, orchestrating the functions of smart sensors and actuators, facilitating data collection, analysis, and communication with cloud-based applications. With billions of these MCUs already in operation, the burgeoning demand for smart living and working environments is set to propel their deployment even further.

Patrick Aidoune, General Manager of STMicroelectronics' General-Purpose MCU Division, emphasized the significance of minimizing energy consumption in pervasive devices to curtail wastage. The latest STM32U0 microcontroller series represents a significant advancement in ultra-low-power technologies, enabling devices in various sectors, including industrial, medical, and consumer electronics, to operate more efficiently while offering enhanced features and cost-effective solutions.

The STM32U0 MCUs achieve remarkable energy efficiency through innovative design techniques and advanced manufacturing processes. Noteworthy features include ultra-low static power consumption in standby mode and exceptional wake-up performance, allowing the MCU to spend extended periods in power-saving sleep modes, thus reducing average energy consumption.

Leading customers have already adopted the STM32U0 for diverse applications, such as security cameras for enhanced surveillance with energy savings, long-lasting smoke detectors, and power-conscious functions in water meters. Furthermore, the MCU's integration of an LCD segment display controller enhances cost-effectiveness for devices requiring LCDs, such as thermostats, smart retail labels, access-control panels, and factory automation systems.

In addition to energy efficiency, the STM32U0 series offers robust security features, meeting SESIP Level 3 and PSA Level 1 standards for firmware code protection. Certification ensures compliance with upcoming regulations like the US Cyber Trust Mark and EU Radio Equipment Directive (RED), bolstering trust in product security.

Developers can leverage the STM32U0's ample specifications, including up to 256KB of Flash, package options up to 81 pins, and a 56MHz core speed, to create innovative solutions tailored to diverse applications.

The STM32U0 series is currently in production, with competitive pricing starting at USD 0.68 for 1,000 units. Customers can request samples and explore pricing options through local ST sales offices.
