CAT5401  
Quad Digitally Programmable Potentiometers  
(DPP™) with 64 Taps and SPI Interface  
FEATURES  
DESCRIPTION  
„ Four linear taper digitally programmable  
The CAT5401 is four 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 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.  
potentiometers  
„ 64 resistor taps per potentiometer  
„ End to end resistance 2.5kΩ, 10kΩ, 50kΩ or  
100kΩ  
„ Potentiometer control and memory access via  
SPI interface: Mode (0, 0) and (1, 1)  
„ Low wiper resistance, typically 100Ω  
„ 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  
„ 24-lead SOIC and 24-lead TSSOP  
„ Industrial temperature range  
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.
