Power Supply Terminal. The DS1855 will support supply  
voltages ranging from +2.7V to +5.5V.

Ground Terminal.  
2-Wire serial data interface. The serial data pin is for serial data  
transfer to and from the DS1855. The pin is open drain and may  
be wire-ORed with other open drain or open collector interfaces.  
2-Wire Serial Clock Input. The serial clock input is used to  
clock data into the DS1855 on rising edges and clock data out on  
falling edges.  
Write Protect Input. If set to logic 0, the data in memory and the  
potentiometer wiper setting may be changed. If set to logic 1, both  
the memory and the potentiometer wiper settings will be write  
protected. The WP pin is pulled high internally.  
Address Input. Pins A0, A1, and A2 are used to specify the  
address of each DS1855 when used in a multi-dropped  
configuration. Up to eight DS1855s may be addressed on a single  
2-wire bus.

Address Input.  
High terminal of Potentiometer 0. For both potentiometers, it is  
not required that the high terminal be connected to a potential  
greater than the low terminal. Voltage applied to the high terminal  
of each potentiometer cannot exceed VCC or go below ground.  
High terminal of Potentiometer 1.  
Low terminal of Potentiometer 0. For both potentiometers, it is  
not required that the low terminal be connected to a potential less  
than the high terminal. Voltage applied to the low terminal of each  
potentiometer cannot exceed VCC or go below ground.  
Low terminal of Potentiometer 1.  
Wiper terminal of Pot 0. The wiper position of Potentiometer 0  
is determined by the byte at EEPROM memory location F9h.  
Voltage applied to the wiper terminal of each potentiometer cannot  
exceed the power supply voltage, VCC, or go below ground.  
Wiper terminal of Pot 1. The wiper position of Potentiometer 1  
is determined by the byte at EEPROM memory location F8h.  
No Connect.
