Discovery kit with STM32F469NI MCU

Introduction

The STM32F469I-DISCO Discovery kit (32F469IDISCOVERY) is a complete demonstration and development platform for STMicroelectronics Arm® Cortex®-M4 core-based STM32F469NIH6 microcontroller. This microcontroller features three I2C interfaces, six SPIs with two multiplexed full-duplex I2S interfaces, SDIO, four USART ports, four UART ports, two CAN buses, three 12-bit ADCs, two 12-bit DACs, one SAI, 8 to 14-bit digital camera digital module interface, internal 320+4 Kbytes of SRAM and 2-Mbyte Flash memory, USB HS OTG and USB FS OTG, Ethernet MAC, FMC interface, MIPI DSISM interface, Quad-SPI interface, JTAG debugging support. This Discovery kit offers everything required for users to get started quickly and develop applications easily.

The hardware features on the board help users to evaluate the following peripherals: USB OTG FS, microSD™ card, Audio DAC with headset jack, digital microphones, SDRAM, Quad-SPI Flash memory, 4" TFT LCD using MIPI DSISM interface with capacitive touch panel. The ARDUINO® compatible connectors expand the functionality with a wide choice of specialized shields. The extension header makes it possible to easily connect a daughterboard for specific application. The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer for the STM32 MCU.

2 Ordering information

To order the 32F469IDISCOVERY Discovery kit, refer to Table 1. Additional information is available from the datasheet and reference manual of the target microcontroller.

2.1Product marking

Evaluation tools marked as "ES" or "E" are not yet qualified and therefore they are not ready to be used as reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference design or in production.

"E" or "ES" marking examples of location:

•On the targeted STM32 that is soldered on the board (for illustration of STM32 marking, refer to the section “Package information” of the STM32 datasheet available at www.st.com).

•Next to the evaluation tool ordering part number, that is stuck or silk-screen printed on the board.

This board features a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number and is not available for sales.

In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.

2.2Codification

The meaning of the codification is explained in Table 2.
