Review and Description of the Broadcom BCM5354 Chipset

The BCM5354 achieves the lowest cost and highest performance router system-on-chip (SoC) integration for residential and small office, home office (SOHO) markets OPTIMIZED 802.11G ROUTER WITH BROADRANGE FEATURES.

  • It comes with 240-MHz MIPS32В® CPU core with 16-KB instruction cache, 16-KB data cache, and 1-KB prefetch cache
  • Memory Management Unit (MMU) for high-level Real-Time Operating System (RTOS) support 
  • 2.4-GHz direct conversion radio.
  • USB 2.0 host controller
  • SDRAM controller - 16-bit, 120-MHz SDRAM controller
  • SDR and DDR support
  • USB host interface allows for platform expansion by end users and can support USB print server or Microsoft WindowsВ® Connect Now functionality
  • Supports serial flash
  • Supports high-speed performance mode (HSM) of 125 Mbps that is backward compatible with standard 802.11 b/g Five-port integrated 10/100BASE-TX/FX IEEE 802.3u
  • compliant Auto-MDIX transceivers and LAN/WAN switch
  • Signal processing technology enhances receive controller sensitivity resulting in excellent wireless throughput and range in a home and business environment
  • Eight GPIOs for attachment to various external devices (example: LEDs)
  • One JTAG and two UART ports for debugging development and attaching Data Terminal Equipment (DTE)
  • Low Cost 802.11g Router Flash BCM5354 802.11b/g MAC/PHY/ Radio + Switch DDR/SDR SDRAM Five-Port Magnetics Four-Port LAN 10/100 RJ-45 WAN 10/100 RJ-45 OVERVIEW USB 2.0 Host 1 MB-32MB Flash 2 MB-128MB 120 Mhz DDR/SDR SDRAM 802.11 b/g MAC/PHY/Radio Encore DSP 16 KB I-Cache 16 KB D-Cache PLL GPIO Flash I/F SDRAM I/F 240-MHz MIPS32 with MMU JTAG UART Low-Cost Five-Port Switch 10/100 MAC/PHY 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 SecureEasySetupв
  • Comprehensive wireless network security support that comprises WEP/WPA/WPA2 encryption. The BCM5354 offers industry's most aggressive home router integration and enables the lowest bill of materials (BOM) solution cost.
