Product description
The AX88196B is a non-PCI Ethernet controller with MII for the Embedded Ethernet applications. The AX88196B
supports 8/16-bit SRAM-like host interface, providing a glue-less connection to most common embedded MCUs. The
AX88196B integrates on-chip Fast Ethernet MAC and PHY, which is IEEE802.3 10Base-T and IEEE802.3u
100Base-TX compatible, and 8Kx16 bits embedded SRAM for packet buffering to accommodate high bandwidth
applications. The AX88196B has a wide array of features including support for Twisted Pair Crossover Detection and
Auto-Correction, Wake-on-LAN power management, and IEEE 802.3x and back-pressure flow control. The
programming of AX88196B is simple and compatible with NE2000, so the users don‟t need any modification and can
easily port the software drivers to many embedded systems very quickly. Combining these features with ASIX‟s free
TCP/IP software stack for 8-bit microcontrollers, AX88196B provides the best Ethernet solution for embedded
networking applications.
