Revision 2.2
General Description
The KSZ8851M-series is a single-port controller chip with
a non-PCI CPU interface and is available in 8-bit and 16-
bit bus designs. This datasheet describes the 48-pin LQFP
KSZ8851-16MLL
for
applications
requiring
high-
performance from single-port Ethernet Controller with 8-bit
or 16-bit generic processor interface. The KSZ8851-
16MLL offers the most cost-effective solution for adding
high-throughput
Ethernet
connectivity
to
traditional
embedded systems.
The KSZ8851-16MLL 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 or 16-bit generic host
processor interface and incorporates a unique dynamic
memory pointer with 4-byte buffer boundary and a fully
utilizable 18KB for both TX (allocated 6KB) and RX
(allocated 12KB) directions in host buffer interface.
The KSZ8851-16MLL is designed to be fully compliant with
the appropriate IEEE 802.3 standards. An industrial
temperature-grade version of the KSZ8851-16MLLI and a
qualified AEC-Q100 Automotive version of the KSZ8851-
16MLLU are also available (see “Ordering Information”
section).
LinkMD
Physical signal transmission and reception are enhanced
through the use of analog circuitry. This makes the design
more efficient and allows lower-power consumption. The
KSZ8851-16MLL is designed using a low-power CMOS
process that features a single 3.3V power supply with
options for 1.8V, 2.5V or 3.3V VDD I/O. The device
includes an extensive feature set that offers management
information base (MIB) counters and CPU control/data
interfaces with single shared data bus timing.
The KSZ8851-16MLL 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 KSZ8851-16MLL
supports
Hewlett
Packard
(HP)
Auto-MDIX
thereby
eliminating the need to differentiate between straight or
crossover cables in applications.
