The MC68EN302 is intended for low-end bridge and router applications. It has the three SCCs from the
MC68302, plus an additional Ethernet interface giving it a total of four serial interfaces.
Since the MC68EN302 has both the three SCCs as well as an Ethernet interface, it would be an excellent
choice in an ISDN to Ethernet router.
For remote access dial-in, the MC68EN302 could be used in a dial-up modem that would connect to an
Ethernet LAN.
