STMicroelectronics (ST) enjoyed a 100% sales increase in its microprocessor (MPU) sales in 2022 and is looking to follow up that success with the STM32MP13.

The company cites energy savings, lower operating costs, improved safety and enhanced user experience as the main trends in Smart Buildings, Factory automation and smart cities.

It adds that the latest applications such as industrial automation, communication gateways, payment terminals, appliances, and control panels serving these trends are demanding processors with high software-execution capability, low power consumption, strengthened security, and advanced featureintegration.

Enter the STM32MP13 devices, which says ST are the most affordable yet in its STM32 series. They expand the choices available to product developers, and they support the latest security features for protecting connectedassets.

“Our STM32MP13 single-core MPUs deliver a perfect balance of power consumption, price, and increased capability for applications that demand performance above that of typical high-end embedded microcontrollers,” said Ricardo De Sa Earp, Executive Vice-President General-Purpose Microcontrollers Sub-Group, STMicroelectronics. “With their state-of-the-art security features, these devices accelerate end-product certification according to today’s leading standards including SESIP Level 3 and Payment Card Industry (PCI) PTS/POI 6.0 specifications.”

The new MPUs have a 1GHz ArmCortex-A7 application-processing core, combined with integrated peripherals and power-saving innovations proven in STM32 MCUs. The STM32MP13 ensures a high level of security for connected assets using cryptographic acceleration with SCA robustness/protection, tamper resistance, secure storage, and Arm TrustZonetechnology with TrustedFirmware

(TF-A and OP-TEE) secure processing environments. Peripheral features include a pair of Gigabit Ethernet ports that ease integration in industrial equipment like programmable logic controllers (PLCs).

Development tools and software are common between the STM32MP13 and STM32MP15. They include the fully mainlined OpenSTLinux Distribution with Linux board support package (BSP), drivers, secure bootchain supported by secure manufacturing, and popular application frameworks.

The MPUs are available from STMicroelectronics and its distribution channel partners.
