Typical Operating Circuit
General Description
The DS3231M is a low-cost, extremely accurate, I2C
real-time clock (RTC). The device incorporates a battery
input and maintains accurate timekeeping when main
power to the device is interrupted. The integration of
the microelectromechanical systems (MEMS) resona-
tor enhances the long-term accuracy of the device and
reduces the piece-part count in a manufacturing line.
The DS3231M is available in the same footprint as the
popular DS3231 RTC.
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 1Hz output are provided. Address and
data are transferred serially through an I2C bidirectional
bus. A precision temperature-compensated voltage
reference and comparator circuit monitors the status of
VCC to detect power failures, to provide a reset output,
and to automatically switch to the backup supply when
necessary. Additionally, the RST pin is monitored as a
pushbutton input for generating a microprocessor reset.
See the Block Diagram for more details.
