A precise, temperature-compensated voltage reference and comparator circuit is used to monitor the VCC status, detect power failures, provide a reset output, and automatically switch to a backup power supply when necessary. In addition, the /RST monitor pin can be used as a manual input to generate a Î¼P reset.
ã In addition to high timing accuracy, DS3231 also has some other functions, which expand the additional functions and selection range of the system host. The device integrates a very accurate digital temperature sensor, which can be accessed through the I2C* interface (as time). The accuracy of this temperature sensor is Â±3Â°C. The on-chip control circuit can realize automatic power detection and manage the power switch between the main power supply and the backup power supply (ie, low-voltage battery). If the main power supply fails, the device can continue to provide accurate timing and temperature, and its performance will not be affected. When the main power supply is re-energized or the voltage value returns to the allowable range, the on-chip reset function can be used to restart the system microprocessor.
