New MCU boosts performance and security in next-generation smart applications
The STM32H563 MCU from STMicroelectronics, which features a 250 MHz Arm® Cortex®-M33 core, features the STM32Trust TEE Secure Manager, a service that makes it easier to implement strong security in connected devices.
STMicroelectronics has introduced the performance-oriented STM32H563 microcontroller which offers the cutting-edge security provided by the STM32Trust TEE Security Manager for smart, connected devices.
The new MCU contains the Cortex-M33, an Arm core that blends high performance with security features and energy efficiency. In the STM32H563 implementation, this core runs at 250 MHz and 375 DMIPS, achieving an EEMBC CoreMark® industry-reference score of 1,023.
The security features of the Cortex-M33 core, which complies with the PSA Certified Level 3 and GlobalPlatform SESIP3 security specifications, include the TrustZone® architecture. Building on this, ST has added a range of its own security features.
For instance, the STM32H5 series of which the STM32H563 and the STM32H573 are part is the first to come with system-on-chip (SoC) security services accessed via an industry-standard applications programming interface. This facility, called STM32Trust TEE Secure Manager, saves developers from writing their own security software code, and provides security services that are developed according to industry best practice. This simplifies development while ensuring effective protection.
The SoC security services provided include isolation, cryptography, key storage, and initial attestation. The new devices also provide pre-provisioning credentials programmed in a secure ST factory for seamless registration to various cloud and OEM servers. Other security features are multi-tenant IP protection, and remote lifecycle management of pre-integrated third-party credentials.
The MCU takes advantage of the advanced 40 nm CMOS process technology developed by ST and from improved on-chip power-conversion circuits to keep power consumption low, even when operating at ambient temperature up to 125°C.
