3 fn8160.2 september 26, 2006 principles of operation there are three sections of th e x9116: the input control, counter and decode section; the nonvolatile memory; and the resistor array. the input co ntrol section operates just like an up/down counter. the output of this counter is decoded to turn on a single electronic switch connecting a point on the resistor array to the wiper output. under the proper conditions the contents of t he counter can be stored in nonvolatile memory and retained for future use. the resistor array is comprised of 15 individual resistors connected in series. at either end of the array and between each resistor is an electronic switch that tr ansfers the potential at that point to the wiper pin. the wiper, when at either fixed terminal, acts like its mechanical equivalent and does not move beyond the last position. that is, the counte r does not wrap around when clocked to either extreme. the electronic switches on the device operate in a ?make before break? mode when the wiper changes tap positions. if the wiper is moved several positions, multiple taps are connected to the wiper for t iw (inc to v w change). the r total value for the device can temporarily be reduced by a significant amount if the wiper is moved several positions. when the device is powered-do wn, the last wiper position stored will be maintained in the nonvolatile memory. when power is restored, the content s of the memory are recalled and the wiper is set to the value last stored. instructions and programming the inc , u/d and cs inputs control the movement of the wiper along the resistor array. with cs set low, the device is selected and enabled to respond to the u/d and inc inputs. high to low transitions on inc will increment or decrement (depending on the state of the u/d input) a four bit counter. the output of this counter is decoded to select one of 16 wiper positions along the resistive array. the value of the counter is st ored in nonvolatile memory whenever cs transitions high while the inc input is also high. the system may select the x9116, move the wiper, and deselect the device without havi ng to store the latest wiper position in nonvolatile memory. after the wiper movement is performed as described above and once the new position is reached, the system must keep inc low while taking cs high. the new wiper position will be maintained until changed by the system or until a power-up/down cycle recalls the previously stored data. this procedure allows the syst em to always power-up to a preset value stored in nonvolatile memory; then during system operation, minor adju stments could be made. the adjustments might be based on user preference, system parameter changes due to temperature drift, etc. the state of u/d may be changed while cs remains low. this allows the host system to enable the device and then move the wiper up and down until the proper trim is attained. symbol table mode selection cs inc u/d mode l h wiper up l l wiper down h x store wiper position h x x standby current l x no store, return to standby waveform inputs outputs must be steady will be steady may change from low to high will change from low to high may change from high to low will change from high to low don?t care: changes allowed changing: state not known n/a center line is high impedance x9116
