ST’s STM32H5 series of MCUs leverages an embedded Arm Cortex-M33 core running at 250 MHz and the STM32Trust TEE Security Manager. Aimed at the mid-range class of MCU-based applications, these devices deliver 375 DMIPS for an EEMBC CoreMark industry-reference score of 1023.

In addition to the security provided by the Cortex-M33 core’s TrustZone architecture, ST offers scalable security services accessed via an industry-standard API. The STM32Trust TEE Secure Manager, developed with partner ProvenRun, allows developers to choose from a range of services to achieve the required level of security assurance.

STM32H5 MCUs raise dynamic efficiency to 61 µA/MHz in switched mode (SMPS) and 120 µA/MHz running the linear (LDO) converter (VDD = 3.3 V and 25°C) in run mode with peripherals off. Power management lets developers optimize performance versus power consumption in all operating modes.
