KSZ8851-32MQL

MICREL SEMICONDUCTOR  KSZ8851-32MQL  以太网控制器, 100 Mbps, IEEE 802.3, IEEE 802.3u, 3.1 V, 3.5 V, PQFP, 128 引脚

The is a single-port Controller Chip with a non-PCI CPU interface. The KSZ8851M offers the most cost-effective solution for adding high-throughput Ethernet connectivity to traditional embedded systems. It is a single chip, mixed analog/digital device offering Wake-on-LAN technology for effectively addressing fast Ethernet applications. It consists of a fast Ethernet MAC controller, an 32-bit generic host processor interface and incorporates an unique dynamic memory pointer with 4-byte buffer boundary and a fully utilizable 18kB for both TX allocated 6kB and RX allocated 12kB directions in host buffer interface. It is designed to be fully compliant with the appropriate IEEE 802.3 standards. Physical signal transmission and reception are enhanced through the use of analog circuitry, making the design more efficient and allowing for lower-power consumption.
