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 (see Ordering Information). 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.
