CAT5241  
Quad Digitally Programmable Potentiometers (DPP™)  
with 64 Taps and 2-wire Interface  
TM  
FEATURES  
Automatic recall of saved wiper settings at  
Four 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 range  
End to end resistance 2.5k, 10k, 50kor 100kΩ  
Potentiometer control and memory access via  
2-wire interface (I2C like)  
Low wiper resistance, typically 80  
Nonvolatile memory storage for up to four wiper  
settings for each potentiometer  
DESCRIPTION  
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 CAT5241 is four 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  
wiper control register or any of the non-volatile data  
The CAT5241 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.
