2B25 precision Real time clock module DS3231 AT24C32 IIC (BATTERY NOT INCLUDED)
- DS3231 is a low-cost real-time clock (RTC) that has an integrated temperature-compensated crystal oscillator (TCXO) and I2C working protocol. It also has a backup battery, which provides power when the main supply is cut off.
- It has a crystal resonator, which enhances the long-term accuracy of the device and reduces the piece-part count in a manufacturing line.
- It is available in a 16-pin, 300-millimeter SO package. This RTC module maintains seconds, minutes, hours, dates, months, and yearly information. It changes date and time at the end of the month automatically, including corrections for the leap year.
- This module operates in either a 24-hour or 12-hour format with an AM/PM indicator.
- It consists of a temperature-compensated voltage reference and comparator circuit, which monitors the status of Vcc to detect power failures. This circuit provides a reset output and automatically switches to a backup supply when necessary.
