There is no timing specification associated with this relationship. Data Retention TA = -40 ° C to + 85° C, VDD = 2.7V to 3.65V unless otherwise specified Parameter Min Units Notes Data Retention 10 Years 1 Endurance 1E16 Cycles 2 Notes 1. Data retention is specified at 85 ° C. 2. Endurance is the guaranteed number of read- or write-cycles per address that can be performed while maintaining the specified data retention. It should be impossible to reach this limit for most applications. Power Cycle Timing TA = -40 ° C to + 85° C, VDD = 2.7V to 3.65V unless otherwise specified Symbol Parameter Min Units Notes tPU VDD Min to First Access Start 1 µS tPD Last Access Complete to VDD Min 0 µS Capacitance TA = 25 ° C , f=1.0 MHz, VDD = 3V Symbol Parameter Max Units Notes CI/O Input Output Capacitance 8 pF CIN Input Capacitance 6 pF |
