fn6678 rev 2.00 page 1 of 13 september 9, 2015 fn6678 rev 2.00 september 9, 2015 isl22511 single push button controlled potentiometer (xdcp?) low noise, low power, 32 taps, push button controlled potentiometer datasheet the intersil isl22511 is a thr ee-terminal digitally-controlled potentiometer (xdcp) implem ented by a resistor array composed of 31 resistive ele ments and a wiper switching network. the isl22511 features a push button control, a shutdown mode, as well as an industry-leading utqfn package. the push button control has individual pu and pd inputs for adjusting the wiper. to elimin ate redundancy, the wiper position will automatically incre ment or decrement if one of these inputs is held l onger than one second. forcing both pu and pd low for more than two seconds activates shutdown mode. sh utdown mode disconnects the top of the resistor c hain and moves the wiper to the lowest position, minimizing power consumption. the three terminals a ccessing the resisto r chain naturally configure the isl22511 as a vol tage divider. a rheostat is easily formed by floating an end t erminal or connecting it to the wiper. features ? solid-state non-volatile potentiometer ? push button controlled ? single or auto increment/decrement - fast mode after 1s button press ? autostore of last wiper positio n or manual store of wiper position ? shutdown mode ? 32 wiper tap points - middle scale wiper position on power-up ? low power cmos -v cc = 2.7v to 5.5v - terminal voltage, 0 to v cc - standby current, 3a max ?r total value = 10k ??? 50k ? ? high reliability - endurance: 1,000,000 data c hanges per bit per register - register data retention: 50 years @ t ? +55c ? packages - 8 ld soic - 10 ld utqfn (2.1mmx1.6mm) ? pb-free (rohs compliant) applications ? volume control ? led/lcd brightness control ? contrast control ? programming bias voltages ? ladder networks v cc (supply voltage) control block pu pd v ss (ground) rh rl rw 9 8 7 6 1 2 3 4 nc v ss ase rl v cc pu rh 5 10 pd o rw nc v cc ase pu pd rh v ss 1 2 3 4 8 7 6 5 rl rw o utqfn (top view) soic (top view) ase

isl22511 fn6678 rev 2.00 page 10 of 13 september 9, 2015 power-up and down requirements there are no restri ctions on the powe r-up or power-down conditions of v cc and the voltages applied to the potentiometer pin s provided that v cc is always more positive than or equal to v rh and v rl , i.e., v cc ? v rh, v rl . the v cc ramp rate specification is always in effect. pin descriptions rh and rl the rh and rl pins of the isl22511 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 rh and rl references the relative positi on of the terminal in relation to wiper movement direction. rw the rw pin is the wiper terminal o f the potentiometer which is equivalent to the movable terminal of a mechanical potentiometer. pu the debounced pu input is used to increment the wiper position. an on-chip pull-up holds the pu input high. a switch closure to ground or a low logi c level will, af ter a debounce time, move the wiper t o the next adjacent h igher tap position. pd the debounced pd input is used to decrement the wiper position. an on-chip pull-up holds the pd input high. a switch closure to ground or a low logi c level will, af ter a debounce time, move the wiper t o the next adjacent l ower tap position. ase the debounced ase (autostore enable) pin can be in one of two states: 1. autostore is enabled if ase is held low during power up. 2. autostore is disabled if ase is held high during power- up. a low to high transition w ill initiate a manual store operation. this is for the user who wishes to connect a push button switch to this pin. for every valid push, the isl22511 will store the current wiper position to the eeprom. device operation there are three sections of th e isl22511: the input control, counter and dec ode section; t he eeprom mem ory; and the resistor array. the i nput 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 resist or array to the wiper output. under the prope r conditions, the contents of the counter can be stored in eeprom memory and retained for future use. the resistor array is comprised of 31 individual resistors connect ed in series. at either end of t he array and between each resistor is an electronic switch that transfers the potential at that point to the wiper. the isl22511 is designed to int erface directly to two push button switches for effectively moving the wiper up or down. the pu and pd inputs increment or dec rement a 5-bit counter respectively. the output of this counter is decoded to select one of the thirty-two wiper posit ions along the resistive array . the wiper increment input, pu and the wiper decrement input, pd are both connected to an internal pull-up so that they normally remain high. when pulled low by an external push button switch or a l ogic low level input, the wiper will be switched to the next adjacent tap position. internal debounce circuitry pr events inadvertent switching of the wiper position if pu or pd remain low for less than 15ms, typical. each of the buttons c an be pushed eit her once for a single increment/decrement or continuously for a multiple increments/decrements. the number of increments/decrements of the wiper position depends on how long the button is b eing pushed. when making a continuous push, after the first second, the increment/decrement speed increases. for the first seco nd, the device wil l be in the slow scan mode. then, if the button is held for longer than 1 second , the device will go into the fa st scan mode. as soon as the button is released, the isl22511 will return to a standby condition. if two or more buttons are pressed simultaneously, all commands are ignored upon rel ease of all buttons, except shutdown mode condition. the wiper, when at either fixe d terminal, act s like its mechanical equivalent and does not move bey ond the last position. that is, the counte r does not wrap around when clocked to either extreme. autostore the value of the co unter is stored in eeprom memory after 2 seconds of no ac tivity on pu or pd inputs while ase is enabled (held low). when power is restored, the content of the memory is recalled and the counter resets to the last value stored. if autostore is to be implemented, ase is typically hard wired to v ss . if ase is held high during power-up and then taken low, the wip er will not resp ond to the pu or pd inputs until ase is brought high and held high. manual (push button) store when ase is not enabled (held high ), a push button switch may be used to pull ase low for more than 15ms and released to perform a manual s tore of the wiper position. during memory write cycle al l inputs will be ignored. shutdown mode the isl22511 enters into s hutdown mode if both pu and pd inputs are kept low fo r 2 seconds. in this mode, the resistors array is totally disconnected from its rh pin and the wiper is moved to position closest to r l pin, as shown in figure 13. note, that pu and pd inputs must be pul led low within t db
