Description

The X1205 device is a Real Time Clock with clock/calendar, two polled alarms, oscillator compensation, and battery backup switch.

The oscillator of X1205 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 of X1205 has separate registers for Date, Month, Year and Day-of-week. The calendar is correct through 2099, with automatic leap year correction.
