DESCRIPTION
The X1203 is a Real Time Clock with clock/calendar
circuits and two alarms. The dual port clock and alarm
registers allow the clock to operate, without loss of
accuracy, even during read and write operations.
The clock/calendar provides functionality that is con-
trollable and readable through a set of registers. The
clock, using a low cost 32.768kHz crystal input, accu-
rately tracks the time in seconds, minutes, hours, date,
day, month and years. It has leap year correction,
automatic adjustment for the year 2000 and months
with less than 31 days.
An alarm match of the RTC sets an interrupt flag and
activates an interrupt pin. An alternative alarm function
provides a pulsed interrupt for long time constant time-
bases.
The device offers a backup power input pin. This
Vback pin allows the device to be backed up by a non-
rechargeable battery. The RTC is fully operational from
2.5 to 6 volts.
