IC Plus IP1819

IP1819 is a non-blocking, store-and-forward architecture switch controller, which builds 16-port 10/100Mbps Fast Ethernet MAC and PHY, 3-port Gigabit Ethernet MAC including 2-port RGMII, and one-port RGMII/MII for external CPU in a single chip. IP1819 embeds a 4Mb SRAM for the use of packet buffer. It also provides various 2-wire interfaces, such as CPU interface, SMI, and EEPROM interface, which allow the user to access the internal register, external PHY’s registers and EEPROM data. The serial LED can show the status of each port (such as Link, Speed, Activity and so on) by using 74HC164 or IP403 external device through 2-wire (LED_CLK, LED_DAT) signals driving from IP1819. For avoiding loop occur, IP1819 supports STP, RSTP and MSTP. Even a hardware loop detection mechanism is supported. There are 16K entries in Lookup table. Hashing method can be selected either direct or CRC hashing for MAC addre
