KSZ8841-32MQL
Product Brief
Single-Port Ethernet MAC
Controller with Non-PCI Interface
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.
The KSZ8841-16MQL (or -32MQL) is a single chip, mixed
analog/digital device offering Wake-on-LAN technology for
effectively addressing Fast Ethernet applications. It con-
sists of a Fast Ethernet MAC controller, an 8-bit, 16-bit, and
32-bit generic host processor interface and incorporates
a unique dynamic, fully utilizable 8KB buffer memory for
both TX and RX directions in host buffer interface.
The KSZ8841-16MQL (or -32MQL) is designed to be fully
compliant with the appropriate IEEE 802.3 standards.
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 cable diagnostic
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. A companying
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.
Industrial temperature support (-40°C to +85°C) is also
provided with the KSZ8841-16MVLI.

Application Engineer or salesperson.
