W110 Dual-Speed Ethernet Controller
100Mbps + 10Mbps Ethernet Media Access Controller Mega Macrofunction
DESCRIPTION
The W110 is a 100BASE-T Ethernet Media Access Controller (MAC) mega macrofunction for dual-speed
operation (100Mbps/10Mbps) and an MII interface. Implemented in 0.5m and 0.8m technologies, the
W110 supports a wide range of physical layer (PHY) devices, including both 100Mbps and 10Mbps
devices for wired, optical, and wireless networks, operating in half- or full-duplex mode.
The W110 mega macrofunction is available in various configurations, depending upon customer parti-
tioning requirements. The W110 contains two main submodules, called MAC110 and PCS110. The
MAC110 submodule contains the key transmit/receive functions and performs the CSMA/CD function
specified in ISO/IEC 8802-3: 1993 and the supplemental IEEE standard 802.3u-1995. The PCS110 submod-
ule contains various PHY support modules and MII support.
Potential applications include network interface controllers (NICs), multiport switches, switching rout-
ers, hubs, and test equipment.
The MAC110 submodule contains ~10.1k gates. The final top-level gate count is determined by which
particular PCS option is chosen by the user. The W110M option (transmit and receive function with MII
interface only) contains ~7.1k gates. A gate-level model of the mega macrofunction is available in Verilog
or VHDL.
