Product description
The AX88170 USB to Fast Ethernet/HomePNA Controller is a high performance and highly integrated Controller with embedded 5K*16 bit SRAM. The AX88170 contains a USB interface to host CPU and compliant with USB Standard V 1.0 and V 1.1. The interface between AX88170 and PC Host is compliant with USB Communication Class Specification 1.0. The AX88170 could be used for both 10M/100Mbps Fast Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard and 1M/10M HomePNA standard. The AX88170 supports media-independent interface (MII) or RMII (Reduce MII) interface to simplify the design on implementing Fast Ethernet and HomePNA functions. The chip also provides an optional MII/RMII interface with PHY mode, combine with Ethernet repeater or switch IC can build a multiple ports USB-to-USB bridge application.

1.0 Introduction
1.1 General Description:
The AX88170 USB to Fast Ethernet Controller is a high performance and highly integrated USB bus Ethernet Controller with embedded 5K* 16 bit SRAM. The AX88170 contains a full speed USB interface to host CPU and compliant with USB Communication Class Spec. 1.0. The AX88170 implements both 10Mbps and 100Mbps Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard. The AX88170 supports media -independent interface (MII) or RMII (Reduce MII) interface to simplify the design on implementing Fast Ethernet and HomePNA functions. The chip also provides an optional MII/RMII interface with PHY mode, combines with Ethernet repeater or switch IC can build a multiple ports USB-to-USB bridge application.
AX88170 use s 64-pin LQFP low profile package, 48MHz operation for USB and 25MHz operation for Ethernet, CMOS process with pure 3.3V operation and 5 Volt I/O tolerance.
