Description

The KSZ8841P is a single chip Fast Ethernet MAC controller with a 32 bit/33MHz PCI processor interface. The KSZ8841P is fully compliant with the IEEE 802.3u standard. It will also be available in an Industrial Temperature part, the KSZ8841-PMQLI from Q1 2006.

Features

• Supports 10/100BASE-T/TX/FX

• Supports IEEE 802.3x full-duplex flow control and half-duplex backpressure collision flow control

• Fully compliant to the IEEE 802.3u standard

• Supports burst data transfers

• 8KB internal memory for RX/TX FIFO buffers

• Early TX/RX functions to minimize latency through the device

• Single 25MHz reference clock for both PHY + MAC

Benefits

• Single chip Ethernet controller with IEEE 802.3u support

• 32 bit/33MHz PCI bus for different host processor interfaces
