KSZ8841-16MBL

KSZ8841-16/32MQL/MVL/MVLI/MBL Single-Port Ethernet MAC Controller with Non-PCI Interface Rev. 1.6 General 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. This datasheet describes the KSZ8841M-series of non-PCI CPU interface chips. For information on the KSZ8841 PCI CPU interface chips, refer to the KSZ8841P datasheet. The KSZ8841M 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 memory pointer with 4-byte buffer boundary and a fully utilizable 8KB for both TX and RX directions in host buffer interface. The KSZ8841M is designed to be fully compliant with the appropriate IEEE 802.3 standards. An industrial temperature-grade version of the KSZ8841M, the KSZ8841MVLI, also can be ordered (see “Ordering Information section). LinkMD® 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 c...
