CAT5251  
QuadDigitallyProgrammablePotentiometer(DPP™)with  
256 Taps and SPI 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  
■ 256 resistor taps per potentiometer  
■ End to end resistance 50kΩ or 100kΩ  
■ Standby current less than 1µA  
■ 1,000,000 nonvolatile WRITE cycles  
■ 100 year nonvolatile memory data retention  
■ 24-lead SOIC and 24-lead TSSOP  
■ Industrial temperature range  
■ Potentiometer control and memory access via  
SPI interface  
■ Low wiper resistance, typically 100Ω  
■ Nonvolatile memory storage for up to four wiper  
settings for each potentiometer  
DESCRIPTION  
registers is via a SPI serial bus. 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.  
The CAT5251 is four Digitally Programmable  
Potentiometers (DPPs™) integrated with control logic  
and 16 bytes of NVRAM memory. Each DPP consists of  
a series of resistive elements connected between two  
externallyaccessibleendpoints.Thetappointsbetween  
eachresistiveelementareconnectedtothewiperoutputs  
with CMOS switches. A separate 8-bit control register  
(WCR)independentlycontrolsthewipertapswitchesfor  
each DPP. Associated with each wiper control register  
are four 8-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 CAT5251 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. Itisavailableinthe-40°Cto85°Cindustrial  
operating temperature range and offered in a 24-lead  
SOIC and TSSOP package.
