FEATURES  
DESCRIPTION  
• Nonvolatile solid state potentiometer  
• Single device  
• 100 resistor taps  
• 3-wire serial up/down interface  
• Wiper resistance 200typ. at 5V  
The Xicor X9317 is a nonvolatile digitally controlled  
potentiometer (XDCP). The device consists of a poly-  
crystalline resistor array of 99 segments and CMOS  
switches that connect the wiper terminal to any one of  
the 100 nodes in the array of resistors. The wiper posi-  
tion is defined by the data that is transmitted to the  
device on the 3 terminal serial Up/Down port. A pulse  
on the increment pin causes the wiper to move one  
step to the next wiper position. The direction the wiper  
moves is defined by the logic state on the Up/Down  
pin. A rising edge on the Chip Select pin while the  
increment pin is high causes the present wiper posi-  
tion to be written into an EPROM register. This value is  
recalled on power up restoring the last wiper position  
that was written into the register.  
• R  
values = 1k, 10k, 50kΩ, 100kΩ  
TOTAL  
• Standby current < 1µA  
• V = 5V and 2.7V to 5.5V  
CC  
• Endurance = 100,000 cycles  
• Data retention = 100 years  
• Packages – 8-lead DIP, SOIC,TSSOP, MSOP  
The device can be used in the two terminal mode, with  
the wiper connected to one end of the total resistor, as  
a variable resistor or can be used in the three terminal  
mode as a programmable voltage reference. The  
X9317 can be used to program offset voltages or set  
gains on amplifiers in control circuits.
