This article aims to deliver an in-depth tutorial on the STM32H750VBT6 microcontroller.

Description

The high-performance 32-bit RISC Arm® Cortex®-M7 CPU of STM32H750xB devices operates up to 480 MHz. The Cortex®-M7 core includes a floating-point unit that supports Arm® single-precision and double-precision data-processing instructions. STM32H750xB devices feature a full set of DSP instructions and a memory protection unit (MPU) to improve application security.

The STM32H750xB microcontrollers have 128 Kbytes of flash memory, up to 1 Mbytes of RAM, including 192 Kbytes of TCM RAM, up to 864 Kbytes of user SRAM, and 4 Kbytes of backup SRAM. APB buses, AHB buses, and a multi-layer AXI interface that provides internal and external memory access are also included.

The STM32H750xB microcontroller devices include advanced peripherals and I/Os, including high-speed embedded memories with 128 Kbytes of flash memory and up to 1 Mbyte of RAM. They also include three ADCs, a low-power RTC, two ultra-low-power comparators, two DACs, and numerous timers, including a high-resolution timer, 12 general-purpose 16-bit timers, and two PWM timers for motor control. They include a real random number generator (RNG), a cryptographic acceleration cell, and four digital filters for external sigma-delta modulators. The devices also include standard and sophisticated communication interfaces, making them suitable for various applications.

Memories

Embedded flash memory

The STM32H750xB devices include 128 Kbytes of flash memory for software and data storage. The following is how the flash memory is organized:

128 Kbytes of user flash memory, which includes 128 Kbytes of system flash memory from which the device can boot.

• 2 Kbytes (64 flash words) of user option bytes for user configuration
• Secure access mode

STM32H750xB devices include the Secure access mode, a new enhanced security feature, and other usual memory protection mechanisms (RDP, PCROP). This mode enables the development of user-defined secure services by ensuring code and data security on the one hand and code-safe execution on the other.

Two types of security services are available:

● STMicroelectronics Root Secure Services:

These services are stored in the System memory. They offer a safe way to install firmware and third-party modules. These services are based on cryptographic techniques that use a device-specific private key.

● User-defined secure services:

These services are stored on user flash memory. User secure services include proprietary user firmware update solutions, secure flash integrity checks, and any other sensitive applications requiring high safety. The secure firmware is in specialized user flash memory sections set via option bytes.

Secure services are executed immediately after a reset and preempt all other programs to ensure protected and safe execution. Once performed, the related code and data are no longer accessible. The security services are only available for Cortex®-M7 cores in Secure access mode. The other masters cannot access the option bytes involved in Secure access mode settings or the flash-secured locations.

● Reset and clock controller (RCC)

The D3 domain contains the clock and resets controller. The RCC oversees all clock production, clock gating, and system and peripheral reset control. It allows for a significant degree of flexibility in selecting clock sources and using clock ratios to reduce power consumption. Furthermore, for some communication peripherals that can work with two different clock domains (a bus interface clock or a kernel peripheral clock), the system frequency can be altered without changing the baud rate.

● General-purpose input/outputs (GPIOs)

Each GPIO pin can be configured as an output (push-pull or open-drain, with or without pull-up or pull-down), input, or peripheral alternate function by software. The majority of GPIO pins are shared with alternate digital or analog operations. To further minimize internal noise, power consumption, and electromagnetic emission, all GPIOs are high-current capable and have speed selection. All GPIOs (excluding debug pins) are reset to Analog mode to reduce power consumption. The I/O configuration can be locked by following a specified procedure to prevent unauthorized writing to the I/O registers.
