STMicroelectronics STM32H5 Arm® Cortex®-M33 32-Bit MCU+FPU
STMicroelectronics STM32H5 Arm® Cortex®-M33 32-Bit MCU+FPU extends the STM32 high-performance portfolio and offers enhanced performance and power efficiency. The STMicroelectronics STM32H5 features 128KB of Flash, 32KB of RAM, and WLCSP packages in 25- to 64-pin configurations, as well as LQFP profiles. The line features the Arm Cortex-M33 with a DSP and floating-point unit (FPU) running up to 250MHz. The STM32H5 supports a variety of security features, including the Secure Manager. The Secure Manager is an STMicroelectronics trusted execution environment security framework compliant with Arm Platform Security Architecture (PSA) specifications for Arm Cortex-M (Armv8-M). The Secure Manager aims to simplify the security development cycle of embedded applications by providing ready-to-use security services.
The STM32H5E5 and STM32H5F5 microcontrollers broaden the STM32 portfolio by delivering performance and unlocking unprecedented capabilities. These are the first STM32 MCUs built around the Arm Cortex-M33 core, offering unmatched graphics performance, enhanced power efficiency, faster processing speeds, and advanced connectivity options, all while significantly enhancing security features, without raising costs
The ST STM32H5E5 and STM32H5F5 Microcontrollers are powered by the Arm® Cortex®-M33 core with TrustZone® for Armv8-M, DSP capabilities, and a floating-point unit (FPU). These MCUs feature 3MB to 4MB of Flash memory, 1.5MB of SRAM, and package options ranging from 105- to 225-pins in BGA, WLCSP, and LQFP profiles.
The STM32H5E5 and STM32H5F5 devices support reliable operation at extended temperatures up to 105°C. Compared to related STM32H5E4 devices, the STM32H5E5 and STM32H5F5 add USB HS support with an integrated PHY for high-speed connectivity.
The STM32H5F5 also includes an additional encryption accelerator supporting AES, PKA, and OTFDEC, along with ST-iRoT technology. The STM32H5F5 supports the STM32Trust TEE Secure Manager, available via the X-CUBE-SEC-M-H5 software package, for secure embedded system development.
