Diagram Notes
All start and stop timing parameters apply to both read and write cycles. Clock specifications are identical for read
and write cycles. Write timing parameters apply to slave address, word address, and write data bits. Functional
relationships are illustrated in the relevant data sheet sections. These diagrams illustrate the timing parameters only.

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.
