AX88196B数据手册ASIX中文资料规格书

描述 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.
