• Manufacturer Part Number: dp83016aug
• Description: Falcon Switch 16-port Gigabit Ethernet Switch Engine
• Manufacturer: National Semiconductor Corporation

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.
