DS3232M
±5ppm, I2C Real-Time Clock with SRAM

Maxim Integrated
Detailed Description
The DS3232M is a serial real-time clock (RTC) driven by
an internal, temperature-compensated, microelectrome-
chanical systems (MEMS) resonator. The oscillator pro-
vides a stable and accurate reference clock and main-
tains the RTC to within Q0.432 seconds-per-day accu-
racy from -40NC to +85NC. The RTC is a low-power clock/
calendar with two programmable time-of-day alarms. INT/
SQW provides either an interrupt signal due to alarm
conditions or a 1Hz square wave. The clock/calendar
provides seconds, minutes, hours, day, date, month, and
year information. The date at the end of the month is auto-
matically 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 indi-
cator. The internal registers are accessible though an I2C
bus interface. A temperature-compensated voltage refer-
ence and comparator circuit monitors the level of VCC to
detect power failures and to automatically switch to the
backup supply when necessary. The RST pin provides
an external pushbutton function and acts as an indica-
tor of a power-fail event. Also available are 236 bytes of
general-purpose battery-backed SRAM.
