An embedded processor, otherwise known as an embedded microcontroller, is a type of low-power computer-on-a-chip. The STM32F205VGT6TR is an embedded processor developed by STMicroelectronics (STM). It is designed to provide solutions for applications requiring high performance and real-time processing capabilities. This application note provides an overview of the features, applications, and working principle of the STM32F205VGT6TR.

STM32F205VGT6TR application fields and product specifications

The STM32F205VGT6TR is a 32-bit ARM Cortex-M3 microcontroller. It has a maximum operating frequency of up to 120 MHz and is capable of up to 256KB of internal flash memory. The STM32F205VGT6TR also includes 16-bit SARADC, three I2C (Inter-Integrated Circuit) interfaces, one SPI (Serial Peripheral Interface) bus, two CAN (Controller Area Network) buses, up to 31* fast I/O ports and up to five 12-bit DAC (Digital-to-Analog Converter) converters. This makes the device suitable for a wide range of applications including automotive and industrial systems, consumer electronics, medical applications, green energy solutions and other embedded systems requiring the highest performance, robustness and real-time control.

The STM32F205VGT6TR is available in four different package types to suit a range of specific requirements: DFN6 (3.3x3.3mm), LQFP48 (7x7mm), LQFP64 (10x10mm) and UFBGA48 (5x5mm). The device can operate at temperatures from -40°C to +105°C for extended temperature range applications, such as automotive or industrial environments. The STM32F205VGT6TR also has a maximum operating voltage range of 1.8V to 3.6V and is capable of reverse-battery protection, enabling safe operation in harsh environments.

STM32F205VGT6TR Features

The STM32F205VGT6TR provides a range of features including DMA (direct memory access) support, CAN-FD (CAN with Flexible Data Rate) support, RTC (Real-Time Clock) and WDT (watchdog timer) support. It also includes cryptographic and random number generators, true random number generator (TRNG), as well as a Tamper Detection circuit for secured system operations. Other features include temperature measurement capability, power management, embedded Flash and a special pseudo-instruction to speed up the boot process.

The STM32F205VGT6TR is available with an embedded ARMv7-M based TrustZone security module, allowing code-sharing between the ARM core and a secure coprocessor. It also has integrated support for an advanced debug interface, called Cortex Microcontroller Software Interface Standard (CMSIS), which enables developers to get detailed information on the system states and variables during debug operations. This reduces the debugging time and provides easier access to system status.

STM32F205VGT6TR Working Principle

The STM32F205VGT6TR is an ARM Cortex-M3-based microcontroller, featuring a 32-bit Reduced Instruction Set Computing (RISC) architecture. The core has an optimized instruction set and pipeline for high-performance real-time processing. It also comes with a large choice of peripherals that can be easily integrated into any system or application. It is fully compatible with 3rd party development tools such as high-quality IDEs, libraries, stacks, and compilers.

The STM32F205VGT6TR has an advanced interrupt system, allowing up to 17 interrupt lines with up to 21 interrupt vector tables. When an interrupt is requested, the processor core automatically processes the interrupt vector table and starts executing the appropriate code. This allows the microcontroller to support a high level of real-time processing. It also provides support for sleep, wait and active modes to optimize the power consumption, which helps reduce the total system power consumption.

The STM32F205VGT6TR also includes an advanced power management system, offering low-power modes such as Stop, Standby, VLPS (Very Low-Power Stop), and VLPR (Very Low Power Run). This power management system offers flexibility and can reduce the total system power consumption while still providing high performance. It also helps reduce the overall board size, allowing smaller and more cost-effective designs.

In summary, the STM32F205VGT6TR is a 32-bit ARM Cortex-M3 microcontroller that has a range of features and functions to meet the demands of various applications. It is designed to provide solutions for applications requiring high performance and real-time processing capabilities. The STM32F205VGT6TR is available in four different package types and can operate over an operating voltage range of 1.8V to 3.6V. It has integrated support for an advanced debug interface and an advanced interrupt system that allows up to 17 interrupt lines with up to 21 interrupt vector tables. It also includes advanced power management features to reduce power consumption and is fully compatible with 3rd party development tools.
