STMicro Launches New STM32MP13, STM32WBA52, STM32H5 Microcontrollers

New parts include a high-performance 1GHz Cortex-A7 model, Bluetooth 5.3 Low Energy (BLE) support, and novel security features.

STMicroelectronics has announced new entries in its popular STM32 family of microcontrollers, including the 1GHz STM32MP13, STM32WBA52 with Bluetooth 5.3 Low Energy (BLE), and the STM32H5 series with what it claims is "the world's highest-performing [Arm] Cortex-M33 implementation."

The first of STMicro's new STM32 parts is the STM32MP13, built around a 1GHz Arm Cortex-A7 application-class processing core. Precise specifications depend on model: the STM32MP131 models have only a single Ethernet port; the STM32MP133 range offers CAN FD connectivity and dual Ethernet ports; and the STM32MP135 chips include dual Ethernet, a dedicated parallel display interface, and a 16-bit parallel camera port.

"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," claims STMicro's Ricardo De Sa Earp. "With their state-of-the-art security features, these devices accelerate end-product certification according to today’s leading standards including SESIP [Security Evaluation Standard for IoT Platforms] Level 3 and Payment Card Industry (PCI) PTS/POI 6.0 specifications."

The STM32WBA52, meanwhile, is designed for ultra-low-power Bluetooth projects. Its main processor core is an Arm Cortex-M33 running at 100MHz with a Bluetooth 5.3 Low Energy (BLE) radio offering a +10dBm output power and data rates up to 2Mb/s. each chip can handle 20 simultaneous connections, the company claims, while a deep standby mode keeps the power draw to a minimum without disabling radio communications.

Finally, the STM32H5 family offers an Arm Cortex-M33 running at 250MHz — delivering 1,023 CoreMarks in the EEMBC CoreMark benchmark and a claimed 375 DMIPS of compute, making it what STMicro is claiming as "the world's highest-performing Cortex-M33 implementation." The STM32H5 is most notable, however, for being the first in the STM32 series to include STMicro's STM32Trust TEE Secure Manager, developed in partnership with ProvenRun, which provides an industry-standard application programming interface (API) to on-board secure element and trusted execution environment functionality.

"Our connected world is ready for the enhancements coming with the STM32H5 series, to support advanced services while keeping users, assets, and data secure," claims De Sa Earp of the new parts. "We expect these new MCUs to become the preferred controllers making tomorrow’s smart homes, factories, and cities intelligent, safe, and sustainable."

Mass production of the full STM32MP13 range and selected STM32H5 parts has already begun, STMicro says, with STM32WBA52 samples now available ahead of mass production. Pricing for the parts starts at $1.49 for the STM32WBA52, $1.44 for the STM32H5, and $3.16 for the STM32MP13, all in 10,000-unit bulk quantities.
