www.micrel.com KSZ8841-16MQL KSZ8841-32MQL Product Brief www.DataSheet4U.com Single-Port Ethernet MAC Controller with Non-PCI Interface Description The KSZ8841-series single-port chip includes PCI and non-PCI CPU interfaces, and are available in 8/16-bit and 32-bit bus designs. The KSZ8841-16MQL (or -32MQL) 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, 16-bit, and 32-bit generic host processor interface and incorporates a unique dynamic, fully utilizable 8KB buffer memory for both TX and RX directions in host buffer interface. The KSZ8841-16MQL (or -32MQL) 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. The KSZ8841M is designed using a low-power CMOS process that features a single 3.3V power supply with 5V tolerant I/O. It has an extensive feature set that offers management information base (MIB) counters and CPU control/data interfaces. The KSZ8841M includes a unique cable diagnostic feature called LinkMD®. This feature determines the length of the cabling plant and also ascertains if there is an open or short condition in the cable. A companying software enables the cable length and cable conditions to be conveniently displayed. In addit...
