Description
Dallas DS1225 to FRAM FM16W08 adapter
***Updated for easier manufacture and added decoupling capacitor***
This PCB will let you convert a Dallas DS1225 non-volatile SRAM chip to an FRAM chip that does not require backup batteries.
You can use any FM16W08 SMD variant, and be sure to use thin circular pin type header pins such as the examples below:
https://www.ebay.com/sch/i.html?_nkw=2.54+header+round+pin+single+-socket+-female
https://www.digikey.com/en/products/detail/schmartboard-inc/920-0172-01/9559434
The capacitor is not critical, any 0805 ceramic cap will work, Try to use 50V rated part or higher for best performance.
I just specified the cheapest and most available part from Digikey.
Don't use standard square pin header pins as they won't fit! (And will damage sockets you plug them into).
This has been verified as working in a Tektronix SG5030, as shown here:
