Product Brief
nP3705
2.5-Gbps Network Processor with Integrated Traffic Manager
Benefits
• High integration for Signifi-
cant form factor, cost, and
power savings
• Hardware-based Traffic Man-
ager for guaranteed perfor-
mance
• Software compatibility with
previous generation nP
devices: nP37x0, nP34xx,
nP7250
• Simple programming model
for rapid development and
quick time-to-market
Overview
The nP3705 family of integrated network proces-
sors is a derivative of the nP3700 family that
expands AMCC’s nP5TM technology to lower
speed, cost-sensitive access applications.
Developed over several generations of traffic man-
agement and network processor products, nP5
unites the flexibility of the industry’s highest per-
formance network processing nPcore with the
most widely deployed and mature traffic manage-
ment technology. This unique combination
enables developers to deliver extremely fine-
grained control of subscriber traffic, without
impacting the ability to perform complex protocol
inter-working at media speeds. The nP3705 family

AMCC Network Processors. The single-stage pro-
gramming model dramatically simplifies software
development and troubleshooting for quickest
time-to-market.
Industry Leading Integration and Performance
The nP3705 is a 2.5-Gbps network processing and
traffic management solution. In addition to high-
performance packet processing and fine-grained
traffic management, the nP3705 includes special-
ized coprocessors that perform classification, polic-
ing, and coherent database management for
unparalleled line-rate performance. The devices
are offered in different speed grades to provide a
range of performance and cost options tuned to
the application.
Rapid Application Development
AMCC's nPsoftTM development environment
speeds the development, debugging, and delivery
of feature-rich, wire-speed, Layer 2-7 applications
by combining the simplified nPcoreTM program-
ming model of all AMCC NPUs with open, layered
nPsoft Services, advanced development tools, rich
reference application libraries, and both simulation
and real hardware-based development systems.
Because the nP3705 allows easy API access to on-
chip coprocessors for complex tasks, customer dif-
ferentiating features can be created faster and with
fewer lines of code.
