DS3232M
±5ppm, I2C Real-Time Clock with SRAM
General Description
The DS3232M is a low-cost, extremely accurate, I2C
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
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 neces-
sary. Additionally, the RST pin is monitored as a pushbut-
ton input for generating a microprocessor reset. See the
Block Diagram for more details.
