STM32F429IIH6
Overview
The STM32F429IIH6 is a high-performance ARM Cortex-M4 microcontroller running at 180MHz with an integrated Floating Point Unit (FPU). It features 2MB of Flash memory and 256KB of SRAM, making it suitable for applications requiring significant on-chip storage and complex data processing. This specific variant is housed in a 176+25 pin UFBGA package, offering 140 I/O pins and a dedicated LCD-TFT controller for advanced graphical user interfaces.
Why Choose This Part
The inclusion of the Chrom-ART Accelerator reduces CPU load during graphical operations, enabling smooth 2D rendering. It provides extensive memory density with 2MB of Flash while maintaining a wide operating voltage range of 1.7V to 3.6V. The 180MHz core combined with 140 I/Os and 24 channels of 12-bit ADC provides a high degree of integration for complex system designs.
Applications
Key Specifications
Getting Started
Development typically begins with the STM32CubeF4 software suite and an STM32F429I-DISC1 Discovery kit. Engineers use the STM32CubeMX tool for pinout and clock tree configuration before exporting projects to Keil MDK, IAR EWARM, or the GCC-based STM32CubeIDE. For hardware debugging, an ST-LINK/V2 or V3 probe is required to interface with the chip's JTAG or SWD ports.
