256-Tap Non-Volatile Digital

Potentiometer

Features

• 256 taps for the potentiometer

The iPot™ ISL45021 DCP is a 256-tap,

single-channel non-volatile digital

potentiometer available in 10kΩ, 50kΩ and

• End-to-end resistance available in 10kΩ, 50kΩ and 100kΩ

• Selectable output buffer for each channel

100kΩ end-to-end resistances. These devices can be used

as a three-terminal potentiometer or as a two terminal

variable resistor in a wide variety of applications.

• SPI Serial Interface for data transfer and potentiometer

control

• Daisy-chain operation for multiple devices (10-pin TSSOP

package only)

The output of the potentiometer is determined by the wiper

position, which varies linearly between VA and VB terminal

according to the content stored in the volatile Tap Register

(TR). The settings of the TR can be provided either directly

by the user through the industry standard SPI interface, or

by the non-volatile memory (NVMEM0~3) where the

previous settings are stored. When changes are made to the

TR to establish a new wiper position, the value of the setting

can be saved into any non-volatile memory location

(NVMEM0~3) by executing a NVMEM save operation. Upon

powerup the content of the NVMEM0 is automatically loaded

to the Tap Register.

• Nonvolatile storage of four wiper positions per channel

with power-on recall from NVMEM0

• Low standby current (1µA Max. with output buffer inactive)

• Endurance 100K typical stores per bit

• Register Data Retention 100 years

• Industrial temperature range: -40°C ~ 85°C

• Wide operating voltage range: 2.7V ~ 5.5V

• Package options:

- 8-pin MSOP, 8-pin SOIC, 8-pin PDIP

The ISL45021 contains a single potentiometer in 8-pin PDIP,

SOIC, MSOP or 10 pin TSSOP packages and can operate

over a wide operating voltage range from 2.7V to 5.5V. A

selectable output buffer is built-in for those applications

where an output buffer is required.
