DS3231MPMB1 Peripheral Module
General Description
The DS3231MPMB1 peripheral module provides the nec-
essary hardware to interface the DS3231M real-time clock
(RTC) to any system that utilizes PmodK-compatible
expansion ports configurable for I²C communication.
The IC is a low-cost and extremely accurate I²C RTC.
The device incorporates a battery input and maintains
accurate timekeeping when main power to the device is
interrupted. The integration of the microelectromechani-
cal systems (MEMS) resonator enhances the long-term
accuracy of the device and reduces the piece-part count
in a manufacturing line. The device is available in the
same footprint as the popular DS3231 RTC.
Refer to the DS3231M IC data sheet for detailed informa-
tion regarding operation of the IC.
