D.C. OPERATING CHARACTERISTICS (Over the recommended operating conditions unless otherwise specified.)
ENDURANCE AND DATA RETENTION
CAPACITANCE
POWER-UP TIMING
A.C. TEST CONDITIONS
Notes: (6) This parameter is not 100% tested
(7) tPUR and tPUW are the delays required from the time the (last) power supply (VCC-) is stable until the specic instruction can be
issued. These parameters are periodically sampled and not 100% tested.
