Hex Nonvolatile Potentiometer with  
I/O and Memory  
General Description  
Features  
The DS3930 contains six 256-position nonvolatile (NV)  
potentiometers, 64 bytes of NV user EEPROM memory,  
and four programmable NV I/O pins. The six poten-  
tiometers all share a common low side. The potentiome-  
ters are separated into two groups of three 50k  
potentiometers in parallel. Each group of three poten-  
tiometers shares a common high side and forms an  
equivalent resistance of 16.6k(three 50kpoten-  
tiometers in parallel).  
Six 256-Position NV Potentiometers  
Four General-Purpose NV I/O Pins
