FEATURES  
DESCRIPTION  
Compatible with X9C102/103/104/503  
Low Power CMOS  
The Xicor X9312 is a solid state nonvolatile potentiom-  
eter and is ideal for digitally controlled resistance trim-  
ming.  
—Active Current, 3mA Max  
—Standby Current, 1mA Max  
99 Resistive Elements  
The X9312 is a resistor array composed of 99 resistive  
elements. Between each element and at either end are  
tappointsaccessibletothewiperelement. Thepositionof  
the wiper element is controlled by the CS, U/D, and INC  
inputs. The position of the wiper can be stored in nonvola-  
tile memory and then be recalled upon a subsequent  
power-up operation.  
—Temperature Compensated  
±20% End to End Resistance Range  
— 0 to +15V Range  
100 Wiper Tap Points  
—Wiper Positioned via Three-Wire Interface  
—Similar to TTL Up/Down Counter  
—Wiper Position Stored in Nonvolatile  
Memory and Recalled on Power-Up  
100 Year Wiper Position Data Retention  
X9312Z = 1KΩ  
The resolution of the X9312 is equal to the maximum  
resistance value divided by 99. As an example, for the  
X9312U (50K) each tap point represents 505.  
All Xicor nonvolatile memories are designed and tested  
for applications requiring extended endurance and data  
retention.  
X9312W = 10KΩ  
X9312U = 50KΩ  
X9312T = 100KΩ
