,,,,,,,,,,,,,,,,,,,,,,General,Descri5tion

The DS3231M is a low-cost, extremely accurate, I C

,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Features

S Timekeeping Accuracy Q5ppm (Q0.432 Second/

Day) from -40NC to +85NC

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.

S Battery Backup for Continuous Timekeeping

S Low Power Consumption

S Footprint and Functionally Compatible to DS3231

S Complete Clock Calendar Functionality Including

Seconds, Minutes, Hours, Day, Date, Month, and

Year with Leap Year Compensation Up to Year

2100

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

S Two Time-of-Day Alarms

S 1Hz and 32.768kHz Outputs

S Reset Output and Pushbutton Input with

bus. A precision temperature-compensated voltage

reference and comparator circuit monitors the status of

S Digital Temp Sensor with Q3NC Accuracy

S -40NC to +85NC Temperature Range

S 16-Pin SO (300 mils) Package

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.
