cycled to the device, the wiper setting that was just
stored is the setting loaded on power-up.
Wiper storage does not have to occur immediately after
a change in wiper position. At anytime the current wiper
position can be stored to the EEPROM by simply issu-
ing a low pulse to the CS pin for tCLP while the INC pin
remains in a high state. The wiper does not move dur-
ing this action and the current wiper setting is stored in
EEPROM after tWST.
For applications that require a specific wiper setting to
be loaded on power-up and never changed, write the
desired wiper setting to the EEPROM, then tie CS to
VCC. Every time power is cycled to the DS4301, the
desired wiper setting is loaded from EEPROM, and
since CS is tied to VCC, no changes can be made to
the wiper setting.
EEPROM Characteristics
There is a limit to the number of times the EEPROM can
be written to before a wear-out occurs (see the
Nonvolatile Memory Characteristics table). After EEP-
ROM wear-out occurs, the wiper can still be adjusted,
however accurately storing the wiper position is no
longer possible. When power is removed from the part,
the current wiper position is lost. Upon power-up, the
wiper setting stored in EEPROM is loaded within tWLT of
VCC reaching a stable voltage level greater than or
equal to VCC MIN. If EEPROM wear-out has occurred,
the wiper setting that is loaded is unknown.
Application Information
To achieve the best results when using the DS4301,
decouple the power supply with a 0.01F or 0.1F
capacitor. Use a high-quality ceramic surface-mount
capacitor when possible. Surface-mount components
minimize lead inductance, improving performace.
Ceramic capacitors tend to have adequate high-
frequency response for decoupling applications.
