Detailed Description
The DS3930 contains six NV potentiometers with 64
bytes of NV user memory (EEPROM), and four pro-
grammable NV I/O pins. Figure 1 is a functional dia-
gram of the DS3930.
Potentiometers
The six potentiometers share a common low side and
are separated into two groups of three potentiometers,
each group sharing a common high side. The six 256-
position potentiometers are controllable using six 8-bit
EEPROM registers through the 2-wire interface.
