General Description

The DP83016 (Falcon switch) is a wirespeed, full featured
16-port Gigabit Ethernet Switch-On-a-Chip with several
integrated management interfaces, which supports both,
copper and optical PHYs.

The DP83016 provides non-blocking, wire-speed Gigabit
performance on all ports and supports both managed and
unmanaged operation.

The DP83016 minimizes total system cost. It offers the
most cost effective 16 port Gigabit switch solution in the
market by removing the need for external memory. Further-
more, it eliminates the requirement for a configuration
EEPROM.

An on-chip 256kB frame buffer allows for an extremely
simple system design.

Using only two DP83016 devices, 24-port Gigabit Switch
designs are possible.

The DP83016 forwards frames at layer 2 based on informa-
tion from layer 2 through layer 4. It supports programmable
classification and prioritization to enable enhanced Quality
of Service (QoS) support for real time applications such as
Voice-over-IP (VoIP).

Targeted at desktop/workgroup LAN connectivity, the
DP83016 offers new levels of integration and performance
for Gigabit Ethernet switch applications.

The DP83016 maintains the ability to provide non-blocking
wire-speed Gigabit performance on all ports. The internal
switching engine can process 32 Gbit/s and forward 24 mil-
lion packets per second (Mpps).

The scalable and modular design makes it possible to build
a 16-port or 24-port Gigabit switch using only 1 or 2
devices, respectively. Each port can be configured as tri-
speed port for copper PHYs using (R)GMII or for optical
transceivers using (R)TBI.

The on-chip switching engine with filtering/forwarding func-
tions and queueing capabilities eliminates any require-
ments for external memory devices in the system design.

The DP83016 makes unmanaged designs possible by uti-
lizing a low cost micro-controller for configuration and mon-
itoring purposes - this is accomplished using a simple serial
interface.

Additionally, the DP83016 delivers the ability to make man-
aged designs with a 16-bit parallel CPU interface. This
enables web based or SNMP management. With
enhanced support for routing protocols such as GARP,
GMRP, GVRP and IGMP snooping the DP83016 is an ideal
choice for future switch applications.

The Layer-2 switching engine provides full wire-speed
automatic MAC address learning. The chip also supports
programmable higher layer classification and prioritization
to enable enhanced Quality of Service (QoS) support for
real time applications such as VoIP.
