The RTL8309N is an 8-port 10/100M Ethernet switch controller that integrates memory, eight MACs, and eight physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip.
To simplify the peripheral power circuit, the RTL8309N integrates one LDO regulator to generate 1.0V from a 3.3V input power.
