| FM24C256 drastic endurance difference ?! |
| (1/2) > >> |

Hello, quick question, hopefully simple enough... FM24C256 from Fairchild : Endurance: up to 100K data changes FM24C256 from Ramtron : High Endurance 100 Billion (10^11) Read/Writes How can the same référence, with the same technologue, have SIX ORDERS of magnitudes of difference ?! Am i missing something ? Thanks in advance Nicolas |

Fairchild device is an eeprom |

Great. And... all that because i was not smart enough to guess that there could be two COMPLETELY different functions. How the hell can this happen ?! It's the first time i stumble upon dissimilar references, is it something common or is it rare ? Should i be more attentive when shopping, as i usually only lookup references ? |

You have made the unfortunate mistake of truncating the part number. FM24C256-G for instance is one instance of a Fairchild/Onsemi part. FM24C256N for instance is one instance of a Fairchild/Onsemi part. "FM24C256" is just a type identifier for a non-volatile memory, the technology can be multiple types. Though this is the first case I have seen of mixing FRAM and EEPROM... and I can't lie and say I wouldn't make the same mistake. |

Well, would you blindly replace an M6 hardened steel bolt with some M6 decorative brass bolt? Read the data sheets. I feel no pity, sorry. |
