CAT5113

100-Tap Digitally Program-

mable Potentiometer (DPP)

Description

The CAT5113 is a single digitally programmable potentiometer

(DPP) designed as an electronic replacement for mechanical

potentiometers. 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 CAT5113 contains a 100−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 CAT5113 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.

Pin Description

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 CAT5113 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 CAT5113 operates like a digitally controlled

potentiometer with RH and RL equivalent to the high and low

terminals and RW equivalent to the mechanical

potentiometer’s wiper. There are 100 available tap positions

including the resistor end points, RH and RL. There are 99

resistor elements connected in series between the RH and RL

terminals. The wiper terminal is connected to one of the 100

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 nonvolatile memory using the INC

and CS inputs.

With CS set LOW the CAT5113 is selected and will

respond to the U/D and INC inputs. HIGH to LOW

transitions on INC will 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 CAT5113 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 CAT5113 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 nonvolatile memory.
