STM32H753XIH6 Introduction

The STM32H753XIH6 from STMicroelectronics is a microcontroller from the STM32H753xI line. The high-performance Arm Cortex-M7 32-bit RISC core, which runs at speeds up to 480 MHz, is used in these products. With its advanced features and wide range of peripherals, the STM32H753XIH6 is well-suited for a wide range of applications that need high processing speed and better security.

STM32H753XIH6 Architecture and Core Features

The Arm Cortex-M7 core is at the heart of the STM32H753XIH6 microprocessor. The Cortex-M7 core is a high-performance 32-bit RISC core that can work at up to 480 MHz clock speed. Its advanced design lets it run instructions quickly and do things in real time.

The floating-point unit (FPU) built into the Cortex-M7 core is one thing that makes the STM32H753XIH6 stand out. The FPU supports floating-point calculations in hardware, giving it high accuracy and speed. It follows the IEEE 754 standard and can handle both double-precision and single-precision instructions. This is especially useful in applications like signal processing and control systems that need to do complicated math calculations.

An important part of the STM32H753XIH6 is that it makes program security better. The memory protection unit (MPU) on the microcontroller makes this possible. The MPU gives the microprocessor a way to control and protect access to its memory. It lets you divide up memory areas, set permissions for entry, and set up protection zones. By separating important code and data and preventing unauthorized entry, the MPU makes the embedded system more secure as a whole.

The STM32H753XIH6 microprocessor can do more and is safer because it has an Arm Cortex-M7 core, an FPU that can handle both double-precision and single-precision instructions, and an MPU that protects memory. Because of these features, it is a good choice for applications that need both high speed and strong security.

STM32H753XIH6 Memory and Storage

The STM32H753XIH6 microprocessor has a full memory and storage system to meet the needs of a wide range of applications.

The microprocessor has 2 megabytes of flash memory that is split into two banks. This flash memory lets you store program code and software in a way that doesn’t lose power. The dual-bank setup makes it easy to update the firmware, and a backup bank makes sure that the system works reliably and doesn’t stop.

The STM32H753XIH6 has several types of RAM in addition to flash memory:

“Tightly Coupled Memory” (TCM RAM): It has 192 Kbytes of TCM RAM that works closely with the Cortex-M7 core. TCM RAM has low latency and fast access, which makes it perfect for storing and running important code that needs fast and predictable access times.

● User SRAM

The microprocessor has user SRAM that can hold up to 864 Kbytes. During program processing, this SRAM can be used to store data, allocate stack space, and store dynamic variables.

● Backup SRAM

There are 4 Kbytes of backup SRAM in the STM32H753XIH6. This SRAM keeps its data even if the power goes out or the machine is reset. It is usually used to store important data, like system settings or factors that need to stay the same after a power cycle.

Because there are different kinds of RAM, memory can be divided up in different ways depending on what a program needs. Critical code can be accessed quickly and reliably from TCM RAM, while general-purpose data can be stored in large amounts in user SRAM. Backup SRAM provides essential data persistence during power disruptions.

With its dual-bank flash memory for storing programs and updating firmware and its TCM RAM, user SRAM, and backup SRAM for storing data, the STM32H753XIH6 microcontroller offers a strong and flexible memory and storage solution for a wide range of embedded applications.

STM32H753XIH6 Enhanced I/Os and Peripherals

The STM32H753XIH6 microcontroller has a large selection of I/O interfaces and peripherals that are connected to both the APB (Advanced Peripheral Bus) and AHB (Advanced High-performance Bus) buses, giving it a wide range of capabilities for interacting with external hardware and sensors.

● ADCs and DACs

For precise analog signal acquisition, the microcontroller has three ADCs (Analog-to-Digital Converters). These ADCs allow analog inputs to be transformed into digital values that the microcontroller can process. For accurate analog signal creation, it also has two DACs (Digital-to-Analog Converters). These digital-to-analog converters (DACs) output the corresponding analog voltage for digital values.

● Comparators with Ultra-Low Power

The STM32H753XIH6 includes comparators with ultra-low power. These comparators are made for comparing analog signals and monitoring voltage. They enable effective monitoring and control in power-sensitive applications by detecting specified voltage levels or comparing analog signals to predefined thresholds.

● Timers

To make precise timekeeping, event triggering, and motor control possible, the microcontroller provides a variety of timers.

Twelve 16-bit general-purpose timers are included, and they can be applied to a variety of timing and synchronization applications.

Two PWM (Pulse Width Modulation) timers are dedicated solely to applications for motor control, offering precise control of motor speed and direction.

● Low-Power Timers

The microcontroller also has five low-power timers that use the least amount of power and are ideal for low-energy applications and situations when power is limited.

● Real-Time Clock (RTC)

The STM32H753XIH6 includes an RTC that offers precise timekeeping, date tracking, and event scheduling capabilities. Applications can schedule events, keep up-to-date timestamps, and carry out time-sensitive actions thanks to the RTC.

The microcontroller has a real random number generator (RNG) to increase security. Cryptographic acceleration is also included. For cryptographic operations and safe communication, the RNG creates erratic and genuinely random integers. Additionally, cryptographic acceleration is an option that enables the offloading of cryptographic processes to specialized hardware, improving performance and boosting security in applications that need encryption and decryption capabilities.

● Digital Filters for External Sigma-Delta Modulators (DFSDM)

The STM32H753XIH6 includes digital filters that are especially made for external sigma-delta modulators. Sigma-delta modulators produce analog data that can be precisely processed to improve the precision and quality of the obtained signals.
