Description
The X1243 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 and automatic adjustment for
months with less than 31 days.
An alarm match of the RTC sets an interrupt ag 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 V
BACK
pin
allows the device to be backed up by a non-rechargeable
battery. The RTC is fully operational from 1.8 to 5.5 volts.
The X1243 provides a 2Kbyte EEPROM array, giving a safe,
secure memory for critical user and conguration data. This
memory is unaffected by complete failure of the main and
backup supplies.
