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 I
2
C interfaces, six
SPIs with two multiplexed full-duplex I
2
S 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
me
mory, USB HS OTG and USB FS OTG, Ethernet MAC, FMC interface, MIPI DSI
SM
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 DSI
SM
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 integ
rated ST-LINK/V2-1 provides an embedded
in-circuit debugger and programmer for the STM32 MCU.
