the MPC555 flash is guaranteed to have at least 10 years of data retention after 100 program /erase cycles and an average temperature of 85C. typically it does much better, but this device is specified for very strict automotive applications that accepts no failures. there is an Engineering Bulletin on the Freescale web site that discusses typical flash lifetimes. search for EB619 Typical Endurance for Nonvolatile memory and EB618 Typical Data retention for Nonvolatile Memory. randy > -----Original Message----- > From: [email protected] [mailto:[email protected]] > On Behalf Of samguns_org > > Hi, > According to the user manual, maximum number of program/erase > cycles are 100.
