ASIX AX88796BLF

Product Info

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 °C and industrial grade from -40 to 85 °C. 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'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 provides the best Ethernet solution for embedded networking applications.
