And now we will tell you about the main chips employed in the WRT350N. This router is based on Marvell’s 88F5181 SoC controller.

The chip is also responsible for the router’s USB port. Here is what we could learn about the 88F5181 via the console connector:

The router is equipped with 32 megabytes of system memory in two EM6A9160TS chips from EtronTech.

Here is the memory information we obtained via the terminal:

The router’s firmware is stored in a Samsung K8D6316UTM chip that has a capacity of 8MB.

The network ports of the WRT350N are all based on an 8-port Gigabit Ethernet controller Marvell 88E6131. However, the speed of the WAN port is limited to 100Mbps by the manufacturer. Besides, the 88E6131 has only three physical-level interfaces, so the other two had to be added with individual Marvell 88E1112 chips.

 

The router’s Wi-Fi module is based on an Atheros chipset consisting of an AR2133 RF-module and an AR5416 MAC-controller.

 

Besides the above-mentioned console, there is yet another seat for a console connector on the router’s PCB. It is a JTAG or GPIO interface.
