• Manufacturer Part Number: bcm5841
• Description: Bcm5841 - Multi-gigabit Security Processor
• Manufacturer: Broadcom Corp.

The Broadcom BCM5841 is a follow-up to the BCM5840, the world’s
first single-chip Gigabit security processor. Offering increased
performance, additional functionality, and more flexible interfaces, the
BCM5841 is the most versatile, highest performance IPsec processor in
the world. The BCM5841 is software and mode-compatible with the
BCM5840 processor, thus protecting the software investment of
Broadcom’s current BCM5840 customers.
Flexible enough to span multiple applications and address a variety of
throughput requirements, the BCM5841 is available in four different
versions. The various versions of the BCM5841 are 600 Mbps, 1.2 Gbps,
2.4 Gbps, and 4.8 Gbps. Such versatility allows customers to address an
entire product line’s security requirements with a common security
solution in a cost-effective manner.
The BCM5841 architecture provides backward and forward
compatibility with Broadcom’s BCM5840 Gigabit processor and the
next-generation multi-gigabit solution. Furthermore, migration from the
BCM5840 or BCM5841 to Broadcom’s next-generation solutions is
simplified through a common software API.
Broadcom’s BCM584X common API protects customers’ software
investments while providing the flexibility to migrate to higher
performance, and more highly-integrated, next-generation solutions.
This common API allows customers to migrate from previous

generations to current generations to future generations, while
eliminating the impact on their existing software.
The BCM5841 is able to sustain throughputs of 4.8 Gbps for IPsec
encryption and authentication, regardless of packet size. The innovative
BCM5841 sustains multi-gigabit performance for 3DES-CBC/AES-
CBC and HMAC-SHA-1/HMAC-MD5 IPsec processing.
Flexible enough to work in most applications, the BCM5841 utilizes a
POS-PHY level 3 interface with the ability to seamlessly interact with
Broadcom’s family of broadband processors (BCM1250, BCM1125) via
the FIFO interfaces of the NPU.
The BCM5841 is optimized to function as an IPsec coprocessor that
offloads computationally demanding cryptographic operations from a
host protocol processor. Typical applications might utilize a network
processor (NPU) to perform the IPsec protocol processing, including
Security Policy Database (SPD) lookup, header encapsulation and de-
encapsulation, security association lookup/update, and forwarding to the
BCM5841.
Applications requiring FIPS140-1 level 2 or 3 can benefit from the
ability of the BCM5841’s ability to handle encrypted security
associations. External security associations can be stored encrypted in a
secure manner and forwarded to the BCM5841 for processing without
any performance penalties.
