Product Brief

Ethernet MAC Controller with

PCI Interface

Description

Beneﬁts

The KSZ8841P is a single chip Fast Ethernet MAC con-

troller with a 32 bit/33MHz PCI processor interface. The

KSZ8841P is fully compliant with the IEEE 802.3u stan-

dard. It will also be available in an Industrial Temperature

part, the KSZ8841-PMQLI from Q1 2006.

• Single chip Ethernet controller with IEEE 802.3u

support

• 32 bit/33MHz PCI bus for different host processor

interfaces

• Early TX/RX mode support, to allow for “cut thru” in

Potency Critical Industrial Ethernet or Embedded

Ethernet Application

• Dynamic buffer memory scheme

– Essential for applications such as Video over IP

where image jitter is unacceptable

• Micrel LinkMD^TMcable diagnostic capabilities to

determine cable length and distance to fault, and to

diagnose faulty cables

• Wake-on-LAN technology

• HP Auto MDIX crossover with disable and enable

option

• Enhanced power management feature with power-

down feature

• Industrial Temperature support: –40^oC to +85^oC

Physical signal transmission and reception are enhanced

through the use of analog circuitry that makes the design

more efﬁcient and allows for lower power consumption

and smaller chip die size. The KSZ8841P is designed

with a low-power CMOS design and a high-performance

process that uses a single 3.3V power supply with 5V

tolerant I/O.

The KSZ8841P is a mixed signal analog/digital device of-

fering wake-on-LAN technology. Its extensive feature set

includes management information base (MIB) counters

andCPUcontrol/datainterfacestoeffectivelyaddressboth

current and emerging Fast Ethernet applications.
