	- 2MB internal flash, 1MBytes internal RAM

	- FMC controller to connect SDRAM, NOR and NAND memories

	- Dual mode QSPI

	- SD/MMC/SDIO support

	- Ethernet controller

	- USB OTFG FS & HS controllers

	- I2C, SPI, CAN busses support

	- Several 16 & 32 bits general purpose timers

	- Serial Audio interface

	- LCD controller

	- HDMI-CEC

	- SPDIFRX

	- DFSDM
