Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

It seems that the devices mentioned as having been tested here, are no longer available. Is there a tested/proven alternative?

Hey Cap'n

I did a Google search and came up with:


  Quote  

Supported chips are the Winbond W25Q32, the Winbond W25Q64, and the Winbond W25Q128 providing between 4 and 16 Mbytes of storage. The two bigger chips are as yet untested.

really? they are used in tons of stuff. I recovered one from an old Alcatel router last week.

Winsource has 95,000 of the 4MByte devices in stock if that helps. The price difference between sizes is usually only pennies so I only buy the W25Q128 (16MB). That said I am not going to keep Winbond busy with the quantities I get through. I feel tempted to panic buy now

MatherP did some CSUBS to read/write them and there is a purely MMBasic set on FruitoftheShed which makes them usable on MMX and Arm-mite platforms.
