DS3231 ZS042 AT24C32 IIC Module Precision RTC Real time Clock Memory

Regular price €3,10

Tax included.
DS3231 is a low­cost, extremely accurate I2C real­time clock (RTC), with an integrated
temperature­compensated crystal oscillator (TCXO) and crystal. The device incorporates
a battery input, disconnect the main power supply and maintains accurate timekeeping.
Integrated oscillator improve long­term accuracy of the device and reduces the number of
components of the production line. The DS3231 is available in commercial and industrial
temperature ranges, using a 16­pin 300mil SO package.
RTC maintains seconds, minutes, hours, day, date, month, and year information. Less
than 31 days of the month, the end date will be automatically adjusted, including
corrections for leap year. The clock operates in either the 24 hours or band / AM / PM
indication of the 12­hour format. Provides two configurable alarm clock and a calendar
can be set to a square wave output. Address and data are transferred serially through an
I2C bidirectional bus.

A precision temperature­compensated voltage reference and comparator circuit
monitors the status of VCC to detect power failures, provide a reset output, and if
necessary, automatically switch to the backup power supply. In addition, / RST pin is
monitored as generating μP reset manually.
Save time and high precision addition, DS3231 also has some other features that extend
the system host of additional features and a range of options. The device integrates a
very precise digital temperature sensor, through the I2C * interface to access it (as the
same time). This temperature sensor accuracy is ± 3 ° C. On­chip power supply control
circuit can automatically detect and manage the main and standby power (i.e., lowvoltage
battery) to switch between the power supply. If the main power failure, the device
can continue to provide accurate timing and temperature, performance is not affected.
When the main power re­power or voltage value returns to within the allowable range, the
on­chip reset function can be used to restart the system microprocessor.
