DESCRIPTION

High Terminal

V /R

The high (V /R ) and low (V /R ) 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

to the relative position of the terminal in relation to

wiper movement direction selected by the PU and PD

inputs, and not the voltage potential on the terminal.

Push Down Input

AUTOSTORE Enable Input

ASE

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.

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 resistor 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 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:

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 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 adjacent tap position.

- AUTOSTORE is enabled. When V

powers

down, an automatic store cycle takes place.

- 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 this pin.

For every valid push, the X9511 will store the current

wiper position to the EEPROM.

PIN CONFIGURATION

DIP/SOIC

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 standby condition.
