10. The product Rev D is identified by letter “D” or a dedicated marking code on top of the package.
11. Test conditions according to “A.C. Test Conditions” table.
12. Tested initially and after a design or process change that affects this parameter.
13. t_PU is the delay between the time V_CC is stable and the device is ready to accept commands.
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
