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.

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 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 includes a unique cable diagnostics

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. Accompanying software

enables the cable length and cable conditions to be

conveniently displayed. In addition, the KSZ8841M

supports Hewlett Packard (HP) Auto-MDIX thereby

eliminating the need to differentiate between straight or

crossover cables in applications.

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).
