DESCRIPTION
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.
