General Description
The KSZ8851M-series is a single-port controller chip with
a non-PCI CPU interface and is available in 8/16-bit and
32-bit bus designs. This datasheet describes the 128-pin
PQFP KSZ8851-16/32MQL for applications requiring high-
performance from single-port Ethernet Controller with
8/16-bit
or
32-bit
generic
processor
interface.
The
KSZ8851M offers the most cost-effective solution for
adding high-throughput Ethernet connectivity to traditional
embedded systems.
The KSZ8851M 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 18KB for both TX (allocated 6KB) and RX
(allocated 12KB) directions in host buffer interface.
The KSZ8851M is designed to be fully compliant with the
appropriate
IEEE
802.3
standards.
An
industrial
temperature-grade
version
of
the
KSZ8851M,
the
KSZ8851MQLI is also available (see “Ordering Information
section).
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 KSZ8851M 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 bus timing.
The KSZ8851M includes 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
KSZ8851M
supports
Hewlett
Packard
(HP)
Auto-MDIX
thereby
eliminating the need to differentiate between straight or
crossover cables in applications.
