Ram chip for storage.
Guys,
Can anyone sugest a serial ram chip that would be good to store rapidly changing data. I need to store about 4 bytes 3-5 times a second . So i really dont want to use a eeprom or flash. A battery backup would be optional·cause i could design in a battery.
Any suggestions??
Regards
Peter Rogers

Hi Peter,
Some serial clock chips like the DS1302 have RAM available for
exactly this purpose. They are ready for battery backup.

FRAM actually looks extremely promising ... no battery backup needed, acts
like RAM preforms like EEPROM (without the wearing out aspect), etc. I like
it and look forward to a project that needs it [noparse]:)[/noparse]. I haven't looked them
over yet, but www.ramtron.com has lots of FRAM ads in my product news
catalog .... could be some gotchas ... but I haven't looked for them yet.
Take care all!
