Hi,
Not sure if this is the proper thread to post in, but I figured because it's a question involve flash, it was the right place to be.
I have a Vizio XWR100 wireless router. It's a bit limited with the stock firmware and I want to put a custom firmware on there. The issue is there isn't very much space available. It comes with a 64Mbit NOR flash chip (8MB). The flash chip is a 16-pin SOIC (M25P64-VMF6P). I've attached the datasheet for it.
What I wanted to know if it was possible to replace this with a larger NOR flash chip? I was looking for the largest I could find that's an 16-SOIC. I found a 1Gbit (128MB) NOR flash chip (S70FL01GSAGMFB013). I've attached the datasheet for that as well.
If I had some sort of device to program these flash chips and I were able to extract the contents from the 8MB NOR flash chip and write it to the 128MB NOR flash chip, could I just solder that in with no problems and everything would just work?
The pinouts, from what I can see, seem to be right. Also, the working voltages are the same. There's some speed differences. The 8MB NOR Flash has a 75 MHz clock rate (maximum). The 128MB one has an SCK Clock Frequency for READ and 4READ instructions that's listed as 50MHz max, and it shows 133MHz max for the SCK Clock Frequency for single commands.
I'd really like to put the largest flash chip in there that I can just solder in and have work.
Is this possible?
Thanks!
