Hardware configuration and layout UM1662
1 Hardware configuration and layout
1.1 Features
The STM32F429 Discovery offers the following features:
- STM32F429ZIT6 microcontroller featuring 2 MB of Flash memory, 256 KB of RAM in an LQFP144 package
- On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone ST- LINK/V2 (with SWD connector for programming and debugging)
- Board power supply: through the USB bus or from an external 3 V or 5 V supply voltage
- L3GD20, ST MEMS motion sensor, 3-axis digital output gyroscope
- TFT LCD (Thin-film-transistor liquid-crystal display) 2.4", 262K colors RGB, 240 x 320 dots
- SDRAM 64 Mbits (1 Mbit x 16-bit x 4-bank) including an AUTO REFRESH MODE, and a power-saving
- Six LEDs: – LD1 (red/green) for USB communication – LD2 (red) for 3.3 V power-on – Two user LEDs: LD3 (green), LD4 (red) – Two USB OTG LEDs: LD5 (green) VBUS and LD6 (red) OC (over-current)
- Two pushbuttons (user and reset)
- USB OTG with micro-AB connector
- Extension header for LQFP144 I/Os for a quick connection to the prototyping board and an easy probing
1.2 Microcontroller
The STM32F429ZIT6U device is based on the high-performance ARM® Cortex™-M4 32-bit RISC core operating at a frequency of up to 180 MHz The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The STM32F429ZIT6U device incorporates high-speed embedded memories (2 Mbytes of Flash memory, 256 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
1.3 System requirement
- Windows PC (XP, Vista, 7)
- USB type A to Mini-B USB cable
- ST-LINK/V2
- Supported IDE are EWARM (IAR Embedded Workbench®), MDK-ARM™ and Atollic TrueSTUDIO® Note: Required information to download and install desired IDE and ST-LINK/V2 are detailed in Getting started with STM32F429 Discovery software development tools document.
1.4 Powering up the board
The STM32F429I-DISCO board can be powered up from three sources.
- USB ST-LINK: To power the board from the USB connector CN1, use the 'USB type A to Mini-B' cable and connect it between the host and the board USB connector CN1.
- External sources: DC power supply can be inserted in the GND and 3 V (or 5 V) pin.

1.5 Reset the board
- Push the reset button mounted on the STM32F429I-DISCO.
- Remove and reinsert the USB cable.
- The MCU can also be reset by debuggers.

Figure 4. Package contents
2.2 Programming firmware application
- Install preferred Integrated Development Environment (IDE)
- Install the ST-LINK V2 driver from ST web site
2.2.1 Programming application
To program application (demonstration or example), follow the sequence below: 1. Go under application folder 2. Chose the desired IDE project 3. Double click on the project file (ex. STM32F429I-Discovery_Demo.eww for EWARM) 4. Rebuild all files: Project->Rebuild all 5. Load project image: Project->Debug 6. Run program: Debug->Go Please refer to Getting started with STM32F429 Discovery software development tools for more details.
2.2.2 Run pre-loaded demo
To run and develop any firmware applications on your STM32F429 Discovery board, the minimum requirements are as follows: – Windows PC (XP , Vista, 7) – ‘USB type A to Mini-B' cable, used to power the board (through USB connector CN1) from host PC and connect to the embedded ST-LINK/V2 for debugging and Programming. Additional hardware accessories will be needed to run some applications: – ‘USB type A to Micro-B' cable, used to connect the board (through USB connector CN5) as USB Device to host PC.
