Hardware layout and configuration

The 32F469IDISCOVERY Discovery board is designed around the STM32F469NIH6 (216-
pin BGA package).

Figure 3

illustrates the connection between the STM32F469NIH6 and

the peripherals (SDRAM, Quad-SPI flash memory, color LCD, USB OTG connector, audio,
I

C extension connector, microSD™ card, and embedded ST-LINK).
