Hi Great people of STM32,

I would like to ask if it is possible to work with lan directly with the MCU or I need to buy interface shields that communicate via spi?

but i have seen that stm32 has dedicated pins for ethernet and you can configure sram for it means it can have buffers when that happen can I pipeline on those two rams ram for gpio and ram for ethernet so those two execute simultaneously?

The STM32F100 on the VL-Discovery does not support Ethernet internally, you need some external chips.

The STM32F4-Discovery board *might* support an external PHY, but you'd need to check if all the pins you need actually escape the part and are not used by other attached peripherals. The part itself contains an Ethernet MAC (Media Access Controller)
