IP178C integrates a 9-port switch controller,
SSRAM, and 8 10/100 Ethernet transceivers.
Each of the transceivers complies with the
IEEE802.3,
IEEE802.3u,
specifications. The transceivers are designed in
DSP approach in 0.18um technology; they have
high noise immunity and robust performance.
IP178C operates in store and forward mode. It
supports flow control, auto MDI/MDI-X, CoS, port
base VLAN, bandwidth control, DiffServ, SMART
MAC and LED functions, etc. Each port can be
configured as auto-negotiation or forced 10
Mbps/100 Mbps, full/half duplexmode. Using an
EEPROM or pull up/down resistors on specific
pins can configure the desired options.
Besides an 8-port switch application, IP178C
supports one MII/RMII ports for router application,
which supports 7 LAN ports and one WAN port.
The external MAC can monitor or configure
IP178C by accessing MII registers through SMI.
MII/RMII port also can be configured to be MAC
mode. It is used to interface an external PHY to
work as an 8+1 switch.

IEEE802.3x
