Finally, let’s discuss the hardware components of the DG834N. The router is based on the BCM6358 network processor, which is an improved version of the BCM6348. Both processors belong to Broadcom’s VIPER family and feature the MIPS32 architecture. Besides the processor proper (with separate instruction and data caches), the BCM6358 has an integrated ADSL2+ modem.
Broadcom’s BCM5325 chip is employed as the router's switch. It is a 5-port Fast Ethernet switch with support of VLAN and QoS queues.
The router’s memory is represented by MX29LV320CBTC-70G and EM6A9160TS-5G chips manufactured by Macronix and EtronTech, respectively. The former is a 4MB flash memory chip and the latter is a 16MB chip of DDR400 SDRAM.
The WLAN module is based on Broadcom’s Intensi-fi chipset which consists of a BCM4321 MAC-controller and a BCM2055 RF-module.
Finally, there are two seats for consoles on the router’s PCB. The larger J1 seat is for JTAG and the smaller J10 is for UART.
