DESCRIPTION

The CAT5114 is a single digitally programmable

potentiometer (DPP™) designed as a electronic

replacement for mechanical potentiometers and trim

pots. Ideal for automated adjustments on high volume

production lines, they are also well suited for

applications where equipment requiring periodic

adjustment is either difficult to access or located in a

hazardous or remote environment.

The CAT5114 contains a 32-tap series resistor array

connected between two terminals RH and RL. An up/

down counter and decoder that are controlled by three

input pins, determines which tap is connected to the

wiper, RW. The wiper setting, stored in nonvolatile

memory, is not lost when the device is powered down

and is automatically reinstated when power is

returned. The wiper can be adjusted to test new

system values without affecting the stored setting.

Wiper-control of the CAT5114 is accomplished with

three input control pins, CS

¯¯ , U/D

¯, and INC

¯¯¯. The INC

¯¯¯

input increments the wiper in the direction which is

determined by the logic state of the U/D

¯ input. The CS

¯¯

input is used to select the device and also store the

wiper position prior to power down.

The digitally programmable potentiometer can be

used as a three-terminal resistive divider or as a two-

terminal variable resistor. DPPs bring variability and

programmability to a wide variety of applications

including control, parameter adjustments, and signal

processing.

PIN FUNCTION

INC

¯¯¯: Increment Control Input

The INC

¯¯¯ input moves the wiper in the up or down

direction determined by the condition of the U/D

¯ input.

U/D

¯: Up/Down Control Input

The U/D

¯ input controls the direction of the wiper

movement. When in a high state and CS

¯¯ is low, any

high-to-low transition on INC

¯¯¯ will cause the wiper to

move one increment toward the RH terminal. When in

a low state and CS

¯¯ is low, any high-to-low transition

on INC

¯¯¯ will cause the wiper to move one increment

towards the RL terminal.

RH: High End Potentiometer Terminal

RH is the high end terminal of the potentiometer. It is

not required that this terminal be connected to a

potential greater than the RL terminal. Voltage applied

to the RH terminal cannot exceed the supply voltage,

VCC or go below ground, GND.

RW: Wiper Potentiometer Terminal

RW is the wiper terminal of the potentiometer. Its

position on the resistor array is controlled by the

control inputs, INC

¯¯¯, U/D

¯ and CS

¯¯ . Voltage applied to

the RW terminal cannot exceed the supply voltage,

VCC or go below ground, GND.

RL: Low End Potentiometer Terminal

RL is the low end terminal of the potentiometer. It is not

required that this terminal be connected to a potential less

than the RH terminal. Voltage applied to the RL terminal

cannot exceed the supply voltage, VCC or go below

ground, GND. RL and RH are electrically interchangeable.

CS

¯¯ : Chip Select

The chip select input is used to activate the control

input of the CAT5114 and is active low. When in a

high state, activity on the INC

¯¯¯ and U/D

¯ inputs will not

affect or change the position of the wiper.

DEVICE OPERATION

The CAT5114 operates like a digitally controlled

potentiometer with RH and RL equivalent to the high

and low terminals and RW equivalent to the mecha–

nical potentiometer's wiper. There are 32 available tap

positions including the resistor end points, RH and RL.

There are 31 resistor elements connected in series

between the RH and RL terminals. The wiper terminal

is connected to one of the 32 taps and controlled by

three inputs, INC

¯¯¯, U/D

¯ and CS

¯¯ . These inputs control a

seven-bit up/down counter whose output is decoded

to select the wiper position. The selected wiper

position can be stored in non-volatile memory using

the INC

¯¯¯ and CS

¯¯ inputs.

With CS

¯¯ set LOW the CAT5114 is selected and will

respond to the U/D

¯ and INC

¯¯¯ inputs. HIGH to LOW

transitions on INC

¯¯¯ wil increment or decrement the wiper

(depending on the state of the U/D

¯ input and seven-bit

counter). The wiper, when at either fixed terminal, acts

like its mechanical equivalent and does not move

beyond the last position. The value of the counter is

stored in nonvolatile memory whenever CS

¯¯ transitions

HIGH while the INC

¯¯¯ input is also HIGH. When the

CAT5114 is powered-down, the last stored wiper counter

position is maintained in the nonvolatile memory. When

power is restored, the contents of the memory are

recalled and the counter is set to the value stored.

With INC

¯¯¯ set low, the CAT5114 may be de-selected

and powered down without storing the current wiper

position in nonvolatile memory. This allows the system

to always power up to a preset value stored in non-

volatile memory.
