DS1602

Dallas Real-Time Clocks. The DS1602 can also be driven by an external 32.768kHz oscillator. In this

configuration, the X1 pin is connected to the external oscillator signal and the X2 pin is floated.

VBAT – Battery input for any standard 3V lithium cell or other energy source. Battery voltage must be

held between 2.5V and 3.5V for proper operation. The nominal write-protect trip-point voltage at which

access to the DS1602 is denied is set by the internal circuitry as 1.25 x VBAT nominal. UL recognized to

ensure against reverse charging current when used in conjunction with a lithium battery. See “Conditions

of Acceptability” at www.maxim- ic.com/TechSupport/QA/ntrl.htm.
