General Description

Features

The DS3232M is a low-cost, extremely accurate, I C

S Timekeeping Accuracy ±±ppm ꢀ±(ꢁ0.4 2ecꢂnoꢃ

real-time clock (RTC) with 236 bytes of battery-backed

SRAM. The device incorporates a battery input and

maintains accurate timekeeping when main power to the

device is interrupted. The integration of the microelec-

tromechanical systems (MEMS) resonator enhances the

long-term accuracy of the device and reduces the piece-

part count in a manufacturing line.

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
