Data input/output pin for 3-wire operation. Data input/output for 1-Wire operation: Open drain. (See Parasite Power section.) Clock input pin for 3-wire operation. No connection pins. Ground pin: Either pin can be used for ground. Battery backup input pin: Battery voltage can be 2.8 to 5.5 volts. (See VBATO pin description and Power Control section.) Battery operate input pin for 2.8 to 5.5 volt operation. The VCC & VBATB pins must be grounded when this pin is used to power the chip. (See Power Control section.) 1 Hz square wave output: Open drain. Crystal pins. Connections for a standard 32.768 kHz quartz crystal, EPSON part number C-002RX or C-004R (be sure to request 6 pF load capacitance). NOTE: X1 and X2 are very high impedance nodes. It is recommended that they and the crystal be guard-ringed with ground and that high frequency signals be kept away from the crystal area. See Figure 18 and Application Note 58 for details.
