CAT5221  
Dual Digitally Programmable Potentiometers (DPP™)  
with 64 Taps and 2-wire Interface  
TM  
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  
aseriesof63resistiveelementsconnectedbetweentwo  
externallyaccessibleendpoints.Thetappointsbetween  
eachresistiveelementareconnectedtothewiperoutputs  
with CMOS switches. A separate 6-bit control register  
(WCR)independentlycontrolsthewipertapswitchesfor  
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.
