Discovery kit with STM32F469NI MCU
Introduction
The STM32F469 Discovery kit (32F469IDISCOVERY) is a complete demonstration and
development platform for the STMicroelectronics Arm®Cortex®-M4 core-based
STM32F469NIH6 microcontroller with Chrom-ART Accelerator. 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 DSI®interface, Quad-SPI interface, JTAG debugging support. This Discovery kit offers
everything required for the users to get started quickly and develop applications easily.
The hardware features on the board help the 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®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 microcontroller.
