The Ethernet switch is the only chip to have a cooling heatsink.
The WBR-6000 is based on a SoC controller from Atheros. It is the AR7130 chip, the junior model in the AR7100 series.
Besides a PCI controller, USB host (MAC), two Gigabit Ethernet ports and other components, it incorporates a processor core with the MIPS 24K architecture and a clock rate of 300MHz.
The router is equipped with 16 megabytes of system memory in a Nanya NT5DS8M16FS chip clocked at 200MHz (CL=3).
The firmware is stored in a 25P32V6P chip from STMicroelectronics. We couldn’t find any info about it even at the manufacturer’s website, though. It must have a capacity of 1 megabyte.
All of the router’s ports are based on an Infineon ADM6996FC Ethernet controller.
And finally, the router’s wireless module is based on Atheros’s chipset: an AR5416 MAC-controller and an AR2133 RF-module.
There are three seats for console connectors on the PCB. The two adjacent seats are for UART and JTAG. The function of the first connector is unclear.
