FEATURES  
DESCRIPTION

• Four E POTs in One Package  
• Two-Wire Serial Interface  
• Register Oriented Format  
—Directly Write Wiper Position  
—Read Wiper Position  
The X9241 integrates four nonvolatile E POT digitally  
controlled potentiometers on a monolithic CMOS micro-  
circuit.  
The X9241 contains four resistor arrays, each com-  
posed of 63 resistive elements. Between each element  
and at either end are tap points accessible to the wiper  
elements. The position of the wiper element on the array  
is controlled by the user through the two-wire serial bus  
interface.  
—Store as Many as Four Positions per Pot  
• Instruction Format  
—Quick Transfer of Register Contents to  
Resistor Array  
—Cascade Resistor Arrays  
• Low Power CMOS  
Eachresistorarrayhasassociatedwithitawipercounter  
register and four 8-bit data registers that can be directly  
written and read by the user. The contents of the wiper  
counter register control the position of the wiper on the  
resistor array.  
• Direct Write Cell  
—Endurance - 100,000 Data Changes per Register  
—Register Data Retention - 100 years

• 16 Bytes of E PROM memory  
• 3 Resistor Array Values  
—2KΩ to 50KΩ Mask Programmable  
—Cascadable For Values of 500Ω to 200KΩ  
• Resolution: 64 Taps each Pot  
• 20-Lead Plastic DIP, 20-Lead TSSOP and  
20-Lead SOIC Packages  
Thedataregistermaybereadorwrittenbytheuser. The  
contents of the data registers can be transferred to the  
wiper counter register to position the wiper. The current  
wiper position can be transferred to any one of its  
associated data registers.  
The arrays may be cascaded to form resistive elements  
with 127, 190 or 253 taps.
