Re: romless C3 with extra sram
Is anyone still using the NVSRAM Module anymore that I got from Moates.net?
I think my battery is dead...

Oopsss... I was thinking of a another module... I just Googled that and there is a a battery there.
Like you said:
specs:
• address range
• 0x2000 - 0x2FFF
• non-volatile
• 10 year battery life
Doesn´t it say what battery it is?

Re: romless C3 with extra sram
I believe the battery is built into the NVSRAM chip and once depleted, the whole chip needs to be replaced. That is how the NVSRAM chip works, it has it's own battery backup.
The link to Mouser for the NVSRAM chip says that chip is obsolete. With flash ram becoming popular, I doubt there will be any more NVSRAM chips produced. JMO! Be wary of any old stock or used kits/parts as the battery life of those components cannot be determined. I would get the part number and see if it cross references to any other numbers or manufacturers. GL!
