Industrial temperature range  
End to end resistance 2.5k, 10k, 50kor 100kΩ  
Potentiometer control and memory access via  
SPI interface: Mode (0, 0) and (1, 1)  
Low wiper resistance, typically 80  
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 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 CAT5401 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  
The CAT5401 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.
