Overview

The STM32F439IGT6 is a high-performance ARM Cortex-M4 microcontroller operating at up to 180MHz with an integrated floating-point unit (FPU). It features a Chrom-ART Accelerator for advanced graphics, 1MB of Flash memory, and 256KB of RAM, making it suitable for applications requiring complex processing and rich user interfaces. The device includes a wide array of peripherals including Ethernet, USB OTG, and a dedicated LCD-TFT controller.

Why Choose This Part

The inclusion of the Chrom-ART Accelerator significantly reduces CPU load during graphical operations, allowing for smoother UI transitions at 180MHz. It offers extensive connectivity options including dual CAN, Ethernet, and high-speed USB OTG, supported by 140 I/O pins for complex system integration. The 1.8V to 3.6V supply range and efficient low-power modes enable high-performance processing within tight thermal and power envelopes.

Applications

Industrial Control Panels
Utilizes the integrated LCD-TFT controller and Chrom-ART Accelerator to drive high-resolution human-machine interfaces (HMI).
Networked Gateways
Leverages the 10/100 Ethernet MAC and hardware cryptographic acceleration for secure industrial communication.
Digital Signal Processing
Employs the 180MHz clock speed, FPU, and DSP instructions for real-time audio or sensor data processing.
Secure IoT Endpoints
Uses the true random number generator and cryptographic hardware for encrypted data transmission over USB or Ethernet.

Getting Started

Start development using the STM32CubeF4 software suite and the STM32CubeIDE for a complete toolchain experience. Evaluation is best performed on the STM32F439I-EVAL2 discovery or evaluation boards which break out the LCD and Ethernet interfaces. Ensure the ART Accelerator is enabled in your initialization code to achieve the maximum execution speed from Flash memory.
