CAT5221

Dual Digitally Programmable Potentiometers (DPP™)

with 64 Taps and 2-wire Interface

FEATURES

■ Automatic recall of saved wiper settings at

■ Two linear-taper digitally programmable

power up

potentiometers

■ 2.5 to 6.0 volt operation

■ 64 resistor taps per potentiometer

■ Standby current less than 1µA

■ 1,000,000 nonvolatile WRITE cycles

■ 100 year nonvolatile memory data retention

■ 20-lead SOIC and TSSOP packages

■ Industrial temperature ranges

■ End to end resistance 2.5kΩ, 10kΩ, 50kΩ or 100kΩ

■ Potentiometer control and memory access via

2-wire interface (I²C like)

■ Low wiper resistance, typically 80Ω

■ Nonvolatile memory storage for up to four wiper

settings for each potentiometer

DESCRIPTION

wiper control register or any of the non-volatile data

registers is via a 2-wire serial bus (I²C-like). On power-

up, the contents of the first data register (DR0) for each

ofthefourpotentiometersisautomaticallyloadedintoits

respective wiper control register (WCR).

The CAT5221 is two Digitally Programmable

Potentiometers (DPPs™) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists of

each DPP. Associated with each wiper control register

are four 6-bit non-volatile memory data registers (DR)

used for storing up to four wiper settings. Writing to the

The CAT5221 can be used as a potentiometer or as a

two terminal, variable resistor. It is intended for circuit

level or system level adjustments in a wide variety of

applications.
