CAT5221  
Dual Digital  
Potentiometer (POT)  
with 64 Taps  
and I2C Interface  
Description  
http://onsemi.com  
The CAT5221 is two digital POTs integrated with control logic and  
16 bytes of NVRAM memory. Each digital POT 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  
digital POT. 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 I C 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 (WCR).  
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.
