Dual Digitally Controlled Potentiometers Features (XDCPs™)
Dual solid-state potentiometers
The Intersil X93255 is a dual digitally controlled
Independent Up/Down interfaces
potentiometer (XDCP). The device consists of two resistor
arrays, wiper switches, a control section, and nonvolatile 32 wiper tap points per potentiometer memory. The wiper positions are controlled by individual Wiper position stored in nonvolatile memory and Up/Down interfaces. recalled on power-up 31 resistive elements per potentiometer
A potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching Temperature compensated network. The position of each wiper element is controlled by Maximum resistance tolerance ± 25%
a set of independent CS, U/D, and INC inputs. The position Terminal voltage, 0 to VCC of the wiper can be stored in nonvolatile memory and then

Frequently Asked Questions
How does the device retain its wiper position when power is lost?
The wiper position is stored in nonvolatile memory and will be recalled upon subsequent power-up operation.
What is the recommended operational temperature range for this potentiometer?
The recommended operating temperature range, under specified conditions, is -40°C to +85°C.
What must I ensure regarding the supply voltage during multiple write operations?
When performing multiple write operations, V must not decrease by more than 150mV from its initial value.
Does this device require special handling precautions due to sensitivity?
Yes, these devices are sensitive to electrostatic discharge and proper IC Handling Procedures must be followed.
