2-Wire� RTC Real Time Clock/Calendar

The X1205 device is a Real Time Clock with Clock calendar, two polled alarms, Oscillator compensation, and battery backup Switch
The Oscillator uses an external, low-cost 32.768kHz crystal. All compensation and trim components are integrated on the chip. This eliminates several external Discrete components and a trim capacitor, saving board area and component cost.
The Real-Time Clock keeps track of time with separate Registers for Hours, Minutes, and Seconds. The Calendar has separate Registers for Date, Month, Year and Day-of-week. The calendar is correct through 2099, with Automatic leap year correction.
