KSZ8851-16MLLU

KSZ8851-16MLL/MLLI/MLLU Single-Port Ethernet MAC Controller with 8-Bit or 16-Bit Non-PCI Interface Revision 2.3 General Description The KSZ8851M-series is a single-port controller chip with a non-PCI CPU interface and is available in 8-bit and 16bit bus designs. This datasheet describes the 48-pin LQFP KSZ8851-16MLL for applications requiring highperformance from a single-port Ethernet controller with an 8-bit or 16-bit generic processor interface. The KSZ885116MLL offers the most cost-effective solution for adding high-throughput Ethernet connectivity to traditional embedded systems. The KSZ8851-16MLL 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 8-bit or 16-bit generic host processor interface, and incorporates a 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 the host buffer interface. The KSZ8851-16MLL is designed to be fully compliant with the appropriate IEEE 802.3 standards. An industrial temperature-grade version of the KSZ8851-16MLLI and a qualified AEC-Q100 automotive version of the KSZ885116MLLU are also available (see the Ordering Information section). LinkMD® Physical signal transmission and reception are enhanced through the use of analog circuitry. This makes the design more efficient and allows lower-power consumption. T...
