2-Wire^™RTC

X1203

Real Time Clock/Calendar/Alarm

DESCRIPTION

FEATURES

• 2 alarms—interrupt output

—Settable on the second, minute, hour, day,

month, or day of the week

—Repeat alarm for time base generation

• 2-wire interface interoperable with I²C

—400kHz data transfer rate

• Secondary power supply input with internal

switch-over circuitry

• Low power CMOS

—<1µA operating current

—<3mA active current during program

—<400µA active current during data read

• Typical nonvolatile write cycle time: 5ms

• High reliability

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.

• Small package options

—8-lead SOIC package, 8-lead TSSOP package

The device offers a backup power input pin. This

pin allows the device to be backed up by a non-

BACK

rechargeable battery. The RTC is fully operational from

2.7 to 5.5 Volts and the RTC portion of the X1203

device remains fully operational down to 1.8 Volts.
