System Block Diagram
The BCM5354 integrates a high-performance MIPS32 processor, IEEE
802.11 b/g MAC/PHY, 2.4-GHz direct conversion radio, USB 2.0 host
controller, SDRAM controller, and a configurable five-port Fast
Ethernet (FE) switch.
The BCM5354 provides wireless LAN connectivity that supports data
rates of up to 125 Mbps that is backward-compatible with standard
802.11 b/g.
The BCM5354 supports a WAN connection via its configurable media
interfaces. The per-port programmable four-level priority queues enable
QoS (IEEE 802.1p) for guaranteed bandwidth applications, DiffServ/
TOS, and L2/L3 IGMP snooping. The IEEE 802.1Q VLAN allows
flexible implementation of VLAN grouping and WAN port segregation.
Applications running on the BCM5354 leverage field-proven software
which includes SecureEasySetup™ and comprehensive wireless
network security support that comprises WEP/WPA/WPA2 encryption.
The BCM5354 offers the industry’s most aggressive home router
integration and enables the lowest bill of materials (BOM) solution cost.
Broadcom’s superior technology and innovation also benefit
manufacturers with faster time-to-market, and end products that are
differentiated from the competition through rich features, exceptional
range, and outstanding reliability.
