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

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.
