KSZ8841-16MBLI

Controllers Overview

The KSZ8841-16MBLI is a single-port Ethernet MAC controller with a non-PCI interface, compliant with IEEE 802.3u standards. It supports 10BASE-T and 100BASE-TX speeds with auto-negotiation for full- and half-duplex modes. The device features an 8-bit or 16-bit generic host processor interface, 8 KB internal memory for RX/TX FIFO buffers, and a dynamic buffer memory scheme. It operates on a single 3.3V supply with 5V tolerant I/O buffers and includes LinkMD cable diagnostics, Wake-on-LAN functionality, and HP Auto MDI-X capabilities.
