That reminds me... I was looking at some FRAM datasheets, for RTC+FRAM's actually from Maxim, and they stated a 10-year data retention lifetime. Eeproms are specced at least 40 years, (pic chips) to even 200 years. (some eeproms from Microchip) So looks like FRAM trade's off large numbers of cycle writes with data retention. - -- http://petertodd.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFG7soB3bMhDbI9xWQRAmyCAJ9kuE+lRYKVGlihPFsTI9558weqcQCfZ7Kn Nu3HA24uT0D9J45pIWp0DUE= =Frlw -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
