6. Test conditions according to “A.C. Test Conditions” table.
7. Tested initially and after a design or process change that affects this parameter.
8. t_PU is the delay between the time V_CC is stable and the device is ready to accept commands.
9. Fast−Plus (1 MHz) speed class available for product revision “F”. The die revision “F” is identified by letter “F” or a dedicated marking code
on top of the package.
