CAT5221

Dual Digitally Programmable Potentiometer (DPP™) with

64 Taps and 2-wire Interface

FEATURES

DESCRIPTION

Two linear-taper digitally programmable

The CAT5221 is two Digitally Programmable

Potentiometers (DPPs™) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists

of a series of 63 resistive elements connected

between two externally accessible end points. The tap

points between each resistive element are connected

to the wiper outputs with CMOS switches. A separate

6-bit control register (WCR) independently controls

the wiper tap switches for 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 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 of the four

potentiometers is automatically loaded into its

respective wiper control register (WCR).

potentiometers

64 resistor taps per potentiometer

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

Automatic recall of saved wiper settings at

power up

2.5 to 6.0 volt operation

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 range

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.
