3D Model

STM32H7 devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 480 MHz. The Cortex® -M7 core features a floating point unit (FPU) which supports Arm® double-precision (IEEE 754 compliant) and single-precision dataprocessing instructions and data types. STM32H7 devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security. STM32H7 devices incorporate high-speed embedded memories with a dual-bank Flash memory of 2 Mbytes, up to 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, up to 864 Kbytes of user SRAM and 4 Kbytes of backup SRAM), as well as an extensive range of enhanced I/Os and peripherals connected to APB buses, AHB buses, 2x32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal and external memory access. All the devices offer three ADCs, two DACs, two ultra-low power comparators, a low-power RTC, a high-resolution timer, 12 general-purpose 16-bit timers, two PWM timers for motor control, five low-power timers, a true random number generator (RNG), and a cryptographic acceleration cell. The devices support four digital filters for external sigma-delta modulators (DFSDM). They also feature standard and advanced communication interfaces.

The STM32H7 microcontroller gives ease to developers to easily upgrade existing applications through flexible use of the two cores. By migrating legacy code to the STM32H7 Cortex-M4 with the new GUI running on the Cortex-M7, developers can also add a sophisticated user interface to an application such as a motor drive formerly hosted on a single-core Cortex-M4 MCU. The code development is further simplified using dual core architecture. For security, the MCUs come with pre-installed keys and native secure services including Secure Firmware Install (SFI). SFI allows customers order standard products anywhere in the world and have the encrypted firmware delivered to an external programming company without exposing unencrypted code. The OTA upgrades and patches are secured with built-in support for Secure Boot and Secure Firmware Update (SB-SFU).

The MCUs offer advanced features such as Error Code Correction (ECC) for all Flash and RAM memory to increase safety, multiple advanced 16-bit analog-to-digital converters (ADCs). In addition the MCUs are able to withstand in external ambient-temperature up to 125°C which helps its operation in severe environments. Multiple FD-CAN controllers and Ethernet Controller gives the communication-gateway capabilities. The latest high-resolution timer helps generating precision waveforms. For development, ST has extended the STM32Cube ecosystem by adding STM32CubeH7 firmware modules with application source code, including graphical solutions based on TouchGFX and STemWin graphical-stack library. The new Evaluation, Discovery, and Nucleo boards are also available. Developers can take the benefit of all the standard elements of the STM32Cube development environment including the ST-MC-SUITE motor-control toolkit, STM32Cube-AI machine-learning toolkit, STM32CubeMX, STM32CubeProgrammer and certified partner solutions for STM32.
