DESCRIPTION  
The Xicor X9015 is a 32 tap potentiometer that is vola-  
tile. The device consists of a string of 31 resistors that  
can be programmed to connect the R /V wiper out-  
• Three-wire up/down serial interface  
• V = 2.7V–5V  
CC

• Operating I

put with any of the nodes between the connecting  
resistors. The connection point of the wiper is deter-  
mined by information communicated to the device on  
the 3-wire port. The 3-wire port changes the tap posi-  
tion by a falling edge on the increment pin.The direction  
the wiper moves is determined by the state of the up/  
down pin.The wiper position at power up is Tap #15.  
CC  
• Standby current = 1µA max.  
• R = 10K, 50K, 100KΩ  
TOTAL  
• Packages SOIC-8, MSOP-8  
The X9015 can be used in a wide variety of applica-  
tions that require a digitally controlled variable resistor  
to set analog values.
