It’s been a while since I’ve done a teardown, I have a few modems/routers in the ‘waiting to teardown pile’. Today we have the Netcomm NB5 Rev2 ADSL Modem Router.
The PCB has a date code of 0713 so 13th week of 2007. You can tell it’s fairly old because it has an AC input instead of a DC input. They’ve put the SMD parts very nicely grouped together on the bottom left and not a lot of chips as you would expect for an old modem.
1. Ti ARN Processor
I wasn’t able to find much information on this chip other than a PDF from Ti with a reference to it. Looks to have a 25MHz and 35MHz crystal.

2. Spansion 32Mb Flash Memory
Haven’t seen these around as much as other brands, PDF

And that’s all.
