Product Description
The AX88780 is a high-performance and cost-effective single-chip Fast Ethernet controller for various embedded
systems including consumer electronics and home network markets that require a higher level of network connectivity.
The AX88780 supports 16/32-bit SRAM-like host interface and integrates on-chip Fast Ethernet MAC and PHY, which
is IEEE802.3 10Base-T and IEEE802.3u 100Base-T compatible. The AX88780 supports full-duplex or half-duplex
operation at 10/100Mbps speed with auto-negotiation or manual setting. The AX88780 integrates large embedded SRAM
for packet buffers to accommodate high bandwidth applications and supports IP/TCP/UDP checksum to offload
processing loading from microprocessor/microcontroller in an embedded system.
