The X9511 is a resistor array composed of 31 resistive elements. Between each element and at either end are tap points accessible to the wiper element. The position of the wiper element is controlled by the PU and PD inputs. The position of the wiper can be auto- matically stored in E2 memory and then be recalled upon a subsequent power-on operation. The resolution of the X9511 is equal to the maximum resistance value divided by 31. As an example, for the X9511W (10k) each tap point represents 323. All Intersil nonvolatile products are designed and tested for applications requiring extended endurance and data retention.

X9511 PIN DESCRIPTIONS VH/RH and VL/RL The high (VH/RH) and low (VL/RL) terminals of the X9511 are equivalent to the fixed terminals of a mechan- ical potentiometer. The minimum voltage is -5V and the maximum is +5V. It should be noted that the terminology of VL/RL and VH/RH are in reference to the relative posi- tion of the terminal in relation to wiper movement direc- tion selected by the PU and PD inputs, and not the voltage potential on the terminal. PU The debounced PU input is for incrementing the wiper position. An on-chip pull-up holds the PU input HIGH. A switch closure to ground or a LOW logic level will, after a debounce time, move the wiper to the next adjacent higher tap position. PD The debounced PD input is for decrementing the wiper position. An on-chip pull-up holds the PD input HIGH. A switch closure to ground or a LOW logic level will, after a debounce time, move the wiper to the next adjacent lower tap position. ASE The debounced ASE (AUTOSTORE enable) pin can be in one of two states: VIL - AUTOSTORE is enabled. When VCC powers down, an automatic store cycle takes place. VIH - AUTOSTORE is disabled. A LOW to HIGH will initi- ate 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 X9511 will store the current wiper position to the EEPROM. PIN CONFIGURATION PIN NAMES DEVICE OPERATION There are three sections of the X9511: the input control, counter and decode section; the EEPROM memory; 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. Under the proper 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 connected in series. At either end of the array and between each resistor is an electronic switch that trans- fers the potential at that point to the wiper. The X9511 is designed to interface directly to two push button switches for effectively moving the wiper up or down. The PU and PD inputs increment or decrement a 5-bit counter respectively. The output of this counter is decoded to select one of the thirty-two wiper positions 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 logic LOW level input, the wiper will be switched to the next adjacent tap position. Internal debounce circuitry prevents inadvertent switch- ing of the wiper position if PU or PD remain LOW for less than 40ms, typical. Each of the buttons can be pushed either once for a single increment/decrement or continu- ously for a multiple increments/decrements. The number of increments/decrements of the wiper position depend on how long the button is being pushed. When making a continuous push, after the first second, the incre- ment/decrement speed increases. For the first second the device will be in the slow scan mode. Then if the but- ton is held for longer than 1 second the device will go into the fast scan mode. As soon as the button is released the X9511 will return to a standby condition.

X9511 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. AUTOSTORE The value of the counter is stored in EEPROM memory whenever the chip senses a power-down of VCC while ASE is enabled (held LOW). When power is restored, the content of the memory is recalled and the counter reset to the last value stored. If AUTOSTORE is to be implemented, ASE is typically hard wired to VSS. If ASE is held HIGH during power-up and then taken LOW, the wiper will not respond 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 and released to perform a manual store of the wiper position. RTOTAL with VCC Removed The end to end resistance of the array will fluctuate once VCC is removed. 3 5 6 8 1 2 7 VCC 2k VCC PU PD ASE VH VW VL VSS FIGURE 1.
