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 datasheet
sections. These diagrams illustrate the timing parameters only.

Data Retention
Note: Data retention qualification tests are accelerated tests and are performed such that all three conditions have been applied:
(1) 17 years at a temperature of +55C, (2) 10,000 hours at +105C, and (3) 1,000 hours at +125C.
