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. Physical signal transmission and reception are enhanced through the use of analog circuitry that makes the design more efficient and allows for lower power consumption and smaller chip die size. The KSZ8841P is designed with a low-power CMOS design and a high-performance process that uses a single 3.3V power supply with 5V tolerant I/O.
