Product Description

General Description
The DS3231 is a low-cost, extremely accurate I2C real
time clock (RTC) with an integrated temperature
compensated crystal oscillator (TCXO) and crystal. The
device incorporates a battery input, and maintains accu
rate timekeeping when main power to the device is inter
rupted. The integration of the crystal resonator enhances
the long-term accuracy of the device as well as reduces
the piece-part count in a manufacturing line. The DS3231
is available in commercial and industrial temperature
ranges, and is offered in a 16-pin, 300-mil SO package.
The RTC maintains seconds, minutes, hours, day, date,
month, and year information. The date at the end of the
month is automatically adjusted for months with fewer
than 31 days, including corrections for leap year. The
clock operates in either the 24-hour or 12-hour format
with an
AM/PM indicator. Two programmable time-of
day alarms and a programmable square-wave output
are provided. Address and data are transferred serially
through an I
2C bidirectional bus.
A precision temperature-compensated voltage refer
ence and comparator circuit monitors the status of V
CC
to detect power failures, to provide a reset output, and
to automatically switch to the backup supply when nec
essary. Additionally, the
RST pin is monitored as a
pushbutton input for generating a µP reset.
