STM32F429IGT6 is a microcontroller of STMicroelectronics that based on the high-performance Arm®Cortex®-M4 32-bit RISC core. With FPU, adaptive real-time accelerator (ART Accelerator) allowing 0 wait state execution from Flash memory, frequency up to 180 MHz.

MCU is the core of electronic product development projects. Different microcontrollers have unique features, including package size, RAM and ROM capacity, instruction set, architecture, registers, etc. Therefore, according to different application requirements, the parameters that need to be considered when selecting a microcontroller are also different.

For example, the type of peripheral interface, USB, I2C, SPI, UART and other peripherals are generally used in the system. If the application requires USB or some form of Ethernet, a special note needs to be made. These interfaces have a big impact on how much program space the microcontroller needs to support.

In addition to communication interfaces, there are digital inputs and outputs, analog to digital inputs, PWM, etc. These interfaces will determine the number of pins that the microcontroller needs to provide.

STM32F429IGT6 features standard and advanced communication interfaces.

▪  Up to three I2Cs

▪  Six SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization.

▪  Four USARTs plus four UARTs

▪  An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ULPI)

▪  Two CANs

▪  One SAI serial audio interface

▪  An SDIO/MMC interface

▪  Ethernet and camera interface

▪  LCD-TFT display controller

▪  Chrom-ART Accelerator™

Considering the architectural requirement is important when selecting a MCU for your project. STM32F429IGT6 is based on the Arm® Cortex®-M4 with FPU processor, which is the latest generation of Arm processors for embedded systems. It is a 32-bit RISC processor that features exceptional code-efficiency, delivering the high-performance expected from an Arm core in the memory size usually associated with 8 and 16 bit devices.

Features ART (Adaptive real-time) Accelerator, balances the inherent performance advantage of the Arm® Cortex®-M4 with FPU over Flash memory technologies, which normally requires the processor to wait for the Flash memory at higher frequencies. It also has LCD-TFT controller, which makes it well-suited for embedded graphical user interfaces (GUI).

The STM32F429IGT6 is ideal for applications requiring high-speed processing and robust connectivity. It is well-suited for medical, industrial, and consumer applications.
