New STM32 microprocessor balances performance, power consumption and cost for advanced connected devices

Published Time: 2023-03-15 10:29:22
STMicroelectronics enables safe, secure and sustainable living in the next generation of smart devices with its latest STM32 microprocessors (MPUs).

The STM32MP13 MPU addresses applications that challenge traditional embedded microcontrollers, combining extra performance, a highly secure architecture and energy efficiency in a new class of cost-conscious single-core devices.

1. Energy saving, reduced operating costs, improved safety, and enhanced user experience are the major trends observed in smart buildings, factory automation, and smart cities.

2. The latest applications meeting these trends, such as industrial automation, communication gateways, payment terminals, appliances, and control panels, require processors with high software execution capabilities, low power consumption, enhanced security, and advanced function integration.


ST's new MPU, built on the microcontroller (MCU) know-how and extensive development ecosystem of its STM32 series, meets these expectations and is now expanding the product family with the new STM32MP13 MPU, now available in Mass production. They are by far the most affordable STM32 MPUs, further expanding the range of choices for product developers. The new microprocessor also supports the latest security features for protecting connected assets.

As a key customer of ST's STM32 MPU, HID is integrating the STM32MP13 into a new key design of one of its key access control products. “The main advantages we recognize in this new product include its performance, power and efficiency, its ability to enable all possible powerful cybersecurity attributes and functions, such as its encryption engine and secure boot, and its ability to satisfy some of our demanding peripheral requirements," explained Damon Dageenakis, Director of Access Control Devices PACS at HID.

The new MPU features a 1GHz Arm ® Cortex ® -A7 application processing core, combined with integrated peripherals and power-saving innovations proven in STM32 MCUs. The STM32MP13 ensures high security of connected assets using cryptographic acceleration with SCA robustness/protection, anti-tampering, secure storage and Arm TrustZone ® technology and secure processing environment with trusted firmware (TF-A and OP-TEE). Peripheral features include a pair of Gigabit Ethernet ports for easy integration into industrial equipment such as programmable logic controllers (PLCs).

Development tools and software are common between STM32MP13 and STM32MP15. They include fully mainlined OpenSTLinux distributions, secure boot chains with Linux board support packages (BSPs), drivers, secure manufacturing support, and popular application frameworks. OpenSTLinux Distribution helps speed time to market and save development costs, ensuring seamless software migration and scalability. It can even be extended with Linux real-time functionality thanks to the new X-LINUX-RT extension pack, available for all STM32MP13 and STM32MP15 devices.

More technical information

In addition to bridging the embedded MCU and application processor worlds, the STM32MP13 MPU is built around a complete set of tools to take advantage of the strong MCU ecosystem.

The STM32MP13 is ideal for use with the Qt graphics framework for fast and responsive development of complex user interfaces. Users can take advantage of powerful tools, optimized libraries and easy porting of code for STM32 MCU projects, the result of ST's extensive collaboration with Qt as an ST Authorized Partner.

While gaining the extra processing performance of an MPU, combined with flexible power management, real-time operating system (RTOS) support, and integrated security features and peripherals typically provided by embedded MCUs, STM32MP13 users also benefit from advantages such as a large selection of Package options that help optimize cost and flexibility and allow low-cost PCB designs down to four layers without costly laser vias. ST further eases the designer's workload by providing example PCB layouts.

The STPMIC1 dedicated power management IC (PMIC) for STM32 MPUs is also available, helping developers optimize power consumption to achieve excellent energy ratings and maximize runtime of battery-operated applications. ST PMICs also save bill of materials costs, engineering effort and PCB footprint compared to custom solutions using discrete components.
