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 LinkMDTM cable 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: –40oC to +85oC
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.
