POWER-UP TIMING
POWER-UP AND DOWN REQUIREMENTS
The are no restrictions on the sequencing of the bias supplies VCC, V+, and V- provided that all three supplies reach
their final values within 1msec of each other. At all times, the voltages on the potentiometer pins must be less than V+
and more than V-. The recall of the wiper position from nonvolatile memory is not in effect until all supplies reach their
final value. The VCC ramp rate 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 not 100% tested.
