General Description
The KSZ8842-series of 2-port switches includes PCI and
non-PCI CPU interfaces, and are available in 8/16-bit
and 32-bit bus designs (see Ordering Information).
This datasheet describes the KSZ8842M-series of non-
PCI CPU interface chips. For information on the
KSZ8842 PCI CPU interface switches, refer to the
KSZ8842P datasheet.
The KSZ8842M is the industry’s first fully managed, 2-
port switch with a non-PCI CPU interface. It is based on
a proven, 4
th
generation, integrated Layer-2 switch,
compliant with IEEE 802.3u standards. Also an industrial
temperature
grade
version
of
the
KSZ8842,
the
KSZ8842MVLI,
can
be
ordered
(see
Ordering
Information).
The KSZ8842M can be configured as a switch or as a
low-latency (
≤ 310 nanoseconds) repeater in latency-
critical, embedded or industrial Ethernet applications.
For industrial applications, the KSZ8842M can run in
half-duplex mode regardless of the application.
LinkMD
The KSZ8842M offers an extensive feature set that
includes tag/port-based VLAN, quality of service (QoS)
priority management, management information base
(MIB) counters, and CPU control/data interfaces to
effectively address Fast Ethernet applications.
The KSZ8842M contains: Two 10/100 transceivers with
patented,
mixed-signal,
low-power
technology,
two
media access control (MAC) units, a direct memory
access (DMA) channel, a high-speed, non-blocking,
switch fabric, a dedicated 1K entry forwarding table, and
an on-chip frame buffer memory.
