Product Description
The AX88796B is a low-pin-count (64-pin LQFP) non-PCI Ethernet controller for the Embedded and Industrial
Ethernet applications. The AX88196B is a non-PCI Ethernet controller with MII for the Embedded Ethernet
applications. The AX88796B/AX88196B supports 8/16-bit SRAM-like host interface, providing a glue-less connection
to most common embedded MCUs. The AX88796B/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 AX88796B/AX88196B has a wide array of features
including support for HP Auto-MDIX, Wake-on-LAN power management, and IEEE 802.3x and backpressure flow
control. The AX88796B supports two operating temperature ranges, namely, commercial temperature range from 0 to
70 C and industrial temperature range from -40 to 85 C. The AX88196B just supports one operating temperature
range from 0 to 70 C. The small form factor of AX88796B 64-pin LQFP package helps reduce the overall PCB space.
The programming of AX88796B/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, AX88796B/AX88196B provides the best
Ethernet solution for embedded networking applications.
Target Market
The AX88796B/AX88196B is targeted at a wide range of embedded applications.
Home appliances, portable devices, factory/building automation, industrial equipments, security systems, remote
control/monitoring/management, and streaming media applications such as :
POS, WLAN AP, Broadband Router, IP Camera, content distribution, VoIP, IP STB, digital video recorder,
DVD recorder/player, high definition TV, digital media client/server, home gateway, and IPTV, etc
