HND series

HND (Home Networking Division) series includes BCM42XX, BCM44XX, BCM47XX SoCs

  • BCM4702 802.11b/54gâ„¢ Integrated Wireless AP/Router integrates 125MHz MIPS32â„¢ processor, two 10/100 Ethernet MACs, a PCI/Cardbus host controller, a USB controller and a PCMCIA host
  • BCM4704P integrates a 300MHz MIPS32â„¢ processor core, two 10/100 Ethernet MACs, and a SDRAM controller capable of operating at 133MHz with either DDR or SDRAM. The BCM4704P integrates an on-chip IPSec acceleration engine that can deliver up to 75Mbps of single-pass AES/3DES encryption throughput and supports a broad range of industry-standard security features, such as symmetric-key encryption and authentication algorithms including the 256-bit AES, DES, 3DES, SHA-1, MD5, HMAC-SHA1 and HMAC-MD5
  • BCM4704 pin-compatible version to the BCM4704P without the on-chip IPsec engine
  • BCM4710 pin-compatible and software-compatible with the BCM4702 and adds integrated HomePNAâ„¢ 2.0 functionality
  • BCM4712 802.11b/54gâ„¢ Integrated Wireless AP/Router with 200MHz MIPS32â„¢ processor
  • BCM4780 300MHz MIPS32 Network-Attached Storage Processor

Sentry-5 series

  • BCM5350 integrates a high-performance 200MHz MIPS32â„¢ processor with an on-chip Memory Management Unit (MMU), a 32-bit processor bus, a VPN co-processor, an IEEE 802.11g MAC/baseband controller,DRAM and Flash controller and a 5-port 10/100 Ethernet switch (RoboSwitch) with integrated PHYs. For Layer 2 encryption of wireless data, the BCM5350 contains the same AES/RC4 engine found in the BCM4712. This engine handles WEP, WPA, and 802.11i encryption at 802.11g throughput. For Layer 3 VPNs, the BCM5350 borrows from the Sentry5 line a 75Mbps IPSec engine, which handles AES/3DES/DES encryption plus SHA-1 and MD5 hashing.
  • BCM5830/BCM5834 integrates a high-performance 200 MHz MIPS32â„¢ processor with on-chip Memory Management Unit (MMU), and Instruction-cache and Data-cache. The BCM5834 also integrates a 5-port 10/100 Ethernet switch with integrated PHY (Copper and Fiber). The BCM5830 has two 10/100 Ethernet interfaces with integrated PHY (Copper and Fibre). Additionally, both these devices support general-purpose interfaces such as USB (host/device), UART, GPIO, Flash, and Synchronous/DDR DRAM (up to 512MB), and have a built-in 32-bit 33 MHz PCI 2.2 (host/slave) controller with the ability to drive up to four additional PCI devices.

ADSL series

  • BCM6335 Single-Chip ADSL-to-Ethernet CPE Router. Embedded high-performance MIPS32â„¢ CPU with MMU
  • Broadcom BCM6345 combines an ADSL transceiver and analog front end (AFE) with a MIPS32 CPU, a 10/100 Ethernet interface, a USB 1.1 transceiver, a PCMCIA interface, and a generic expansion bus into a single chip. The embedded MIPS32 CPU, with Broadcom-supplied software, controls the ADSL modem, performs high-performance bridging and routing between the ADSL WAN interface and various LAN interfaces, and allows for customer application development.

Devices are based on the Broadcom SoC
