DS3231 AT24C32 IIC Precision Clock Module with Temperature Sensor, 3.3V/5V Memory as Indicated on PCB, 1 PCS

The DS3231 is available in commercial and industrial temperature ranges and comes in a 30- to 16-pin SO package. The RTC stores information on seconds, minutes, hours, day of the week, date, month, and year. Months with fewer than 31 days will have the end of the month automatically adjusted, including corrections for leap years. The clock working format can be 24-hour or 12-hour with AM/PM indication. It provides two programmable calendar alarms and a programmable square wave output. Address and data are transmitted serially via a bidirectional L2c bus. A temperature-compensated voltage reference and comparator circuit monitors the Vcc status, detects power supply failures, provides a reset output, and automatically switches to backup power if necessary. The monitor pin can be used as a manual input to generate a reset MP. In addition to its high timing accuracy, the DS3231 It also has several other features that extend the capabilities and additional options of the system host. The device integrates a highly digital temperature sensor accessible via the interface (as well as the time). The accuracy of this temperature sensor is ±3°C. The DS3231 is a high-precision, low-cost real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (Tcxo) and crystal. The device includes a battery input to maintain synchronization when the mains power is lost. The integrated crystals improve device longevity and reduce the number of components in production lines. The on-chip control circuit enables automatic power detection and manages power switching between the main power supply and backup power (i.e., low-voltage battery). If the main power supply fails, the device continues to provide synchronization and temperature readings without affecting performance.
