KSZ8851SNL TR

MICREL SEMICONDUCTOR  KSZ8851SNL TR  以太网控制器, 100 Mbps, IEEE 802.3, IEEE 802.3u, 3.1 V, 3.5 V, QFN, 32 引脚

The is a single-chip Fast Ethernet Controller consisting of a 10/100 physical layer transceiver PHY, a MAC and a serial peripheral interface SPI. The KSZ8851SNL is designed to enable an Ethernet network connectivity with any host micro-controller equipped with SPI interface. It offers the most cost effective solution for adding high-throughput Ethernet link to traditional embedded systems with SPI interface. This 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, SPI 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. It includes unique cable diagnostics feature called LinkMD®.
