3 fn8157.4 june 12, 2006 pin descriptions r h /v h and r l /v l the high (r h /v h ) and low (r l /v l ) terminals of the x9015 are equivalent to the fixed terminals of a mechanical potentiometer. the minimum voltage is v ss and the maximum is v cc . the terminology of r l /v l and r h /v h references the relative position of the terminal in relation to wiper movement direction selected by the u/d input, and not the voltage potential on the terminal. r w /v w r w /v w is the wiper terminal and is equivalent to the movable terminal of a mechanical potentiometer. the position of the wiper within the array is determined by the control inputs. the wiper terminal series resistance is typically 200 ? at v cc =5v. at power up the wiper position is at tap #15. (v l /r l =tap #0). up/down (u/d ) the u/d input controls the direction of the wiper movement and whether the tap position is incremented or decremented. increment (inc ) the inc input is negative-edge triggered. toggling inc will move the wiper and either increment or decrement the counter in the direction indicated by the logic level on the u/d input. chip select (cs ) the device is selected when the cs input is low. when cs is returned high while the inc input is also high the x9015 will be placed in the low power standby mode until the device is selected once again. principles of operation there are two sections of the x9015: the input control, counter and decode section; and the resistor array. the input control 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. the resistor array is comprised of 31 individual resistors connected in series. the wiper, when at either fixed terminal, acts like its mechanical equivalent and does not move beyond the last position. that is, the counter does not wrap around when clocked to either extreme. the electronic switc hes 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-down, the wiper position is lost. when power is restored, the wiper is set to tap #15. 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 five bit counter. the output of this counter is decoded to select one of thirty two wiper positions along the resistive array. the system may select the x9015, move the wiper and deselect the device. the new wiper position will be maintained until changed by the system or until a power-up/down cycle. 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. pin names symbol description r h /v h high terminal r w /v w wiper terminal r l /v l low terminal v ss ground v cc supply voltage u/d up/down control input inc increment control input cs chip select control input mode selection cs inc u/d mode lh wiper up ll wiper down hx standby mode hxx standby mode llx normal mode l h wiper up (not recommended) ll wiper down (not recommend- ed) x9015
