DESCRIPTION

The Intersil X9511 is a push button controlled potenti-

ometer that is ideal for push button controlled resis-

tance trim ming.

The X9511 is a resistor array composed of 31 re sistive

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 powe r-on operation.

The resolution of the X9511 is equal to the maximum

resistance value divided by 31. As an example, for the

X9511W (10kΩ) each tap point represen ts 32 3Ω.

All Intersil nonvolatile products are designed and

tested for applications requiring extended endurance

and data retention.

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

mechanical 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 position of the terminal in relation to

wiper movement direction selected by the PU and PD

inputs, and not the volta ge potential on the terminal.

The debounced PU input is for increm enting the wip er

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 t ap position.

The debounce d 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 st ates:

VIL - AUTOSTORE is enabled. When VCC powers

down, an automatic store cycle takes place.

VIH - AUTOSTORE is disabled. A LOW to HIGH will

initiate a manual store operation. This is for the user

who wishes to connect a push button switch to th is 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 oper-

ates 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 r esistor array to the wiper out-

put. 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 elec-

tronic switch that transfers the potential at that point to

the wiper .

The X9511 is designed to interface d irectly 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 posi-

tions 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 adjacen t tap position .

Internal debounce circuitry prevents inadvertent

switching 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/dec-

rement or continuously for a multiple increments/dec-

rements. 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 increment/decrement speed

increases. For the first second the device will be in the

slow scan mode. Then if the button 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 st andby co ndition.

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 extre me.

AUTOSTORE

The value of the counter is stored in EEPROM mem-

ory 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 wire d 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 manu al store of the wiper position.

RTOTAL with VCC Removed

The end to end resistance of the array will fluctuate

once VCC is removed.
