"- for small data/quick access holder: FRAM from Ramtron (use FM1808: 32kbytes Ferroelectric Nonvolatile RAM - 10 Billion(!!!) read/write cycles; 10 years retention without a 3.3 battery); "

I now have a need to remove the 3.3 V battery from the 6 digit cycle counters that we normally use. It now uses a PCF8583 I2C chip as the NV RAM. I think the above FRAM with a write alogorithm that checks if data is changed and THEN only writes should solve my problem.

Thanks for the pointer.
