Description

The AX88796B is a low-pin-count (64-pin LQFP) non-PCI Ethernet controller for the Embedded and Industrial Ethernet applications. The AX88796B supports 8/16-bit SRAM-like host interface, providing a glue-less connection to most common embedded MCUs. The AX88796B 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 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 backpressure flow control. The AX88796B supports two operating temperature ranges, namely, commercial grade from 0 to 70 and industrial grade from -40 to 85 . The small form factor of 64-pin LQFP package helps reduce the overall PCB space. The programming of AX88796B is simple and compatible with NE2000, so the users don&primet need any modification and can easily port the software drivers to many embedded systems very quickly. Combining these features with ASIX&primes free TCP/IP software stack for 8-bit microcontrollers, AX88796B provides the best Ethernet solution for embedded networking applications.
