D.C. OPERATING CHARACTERISTICS (Over the recommended operating conditions unless otherwise specified.)

ENDURANCE AND DATA RETENTION

CAPACITANCE

POWER-UP TIMING

POWER-UP AND DOWN REQUIREMENTS

The are no restrictions on the power-up or power-down conditions of VCC and the voltages applied to the poten-

tiometer pins provided that VCC is always more positive than or equal to VH, VL, and VW, i.e., VCC  VH, VL, VW. The

VCC power-up timing spec is always in effect.

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 specific instruction can be issued.

These parameters are periodically sampled and not 100% tested.
