X9C102/103/104/503DEVICE OPERATIONThere are three sections of the X9C102/103/104/503:the input control, counter and decode section; the non-volatile memory; and the resistor array. The input controlsection operates just like an up/down counter. Theoutput of this counter is decoded to turn on a singleelectronic switch connecting a point on the resistor arrayto the wiper output. Under the proper conditions thecontents of the counter can be stored in nonvolatilememory and retained for future use. The resistor arrayis comprised of 99 individual resistors connected inseries. At either end of the array and between eachresistor is an electronic switch that transfers thepotential at that point to the INC, U/D and CS inputs control the movement of thewiper along the resistor array. With CS set LOW theX9C102/103/104/503 is selected and enabled torespond to the U/D and INC inputs. HIGH to LOWtransitions on INC will increment or decrement(depending on the state of the U/D input) a seven-bitcounter. The output of this counter is decoded toselect one of one-hundred wiper positions along theresistive wiper, when at either fixed terminal, acts like itsmechanical equivalent and does not move beyond thelast position. That is, the counter does not wrap aroundwhen clocked to either value of the counter is stored in nonvolatile memorywhenever CS transistions HIGH while the INC input isalso the X9C102/103/104/503 is powered-down, thelast counter position stored will be maintained in thenonvolatile memory. When power is restored, the con-tents of the memory are recalled and the counter is resetto the value last ION NOTESThe system may select the X9C102/103/104/503, movethe wiper, and deselect the device without having tostore the latest wiper, position in nonvolatile wiper movement is performed as described above;once the new position is reached, the system would thekeep INC LOW while taking CS HIGH. The new wiperposition would be maintained until changed by thesystem or until a power-down/up cycle recalled thepreviously stored would allow the system to always power-up to apreset value stored in nonvolatile memory; then duringsystem operation minor adjustments could be adjustments might be based on user preference:system parameter changes due to temperature The state of U/D may be changed while CS remainsLOW.

If the wiper is moved severalpositions, multiple taps are connected to the wiper fortIW (INC to VW change).
