Description: |
-
100% brand new and high quality
-
Low-cost, extremely accurate I2C real-time clock (RTC),
with an integrated temperature-compensated crystal oscillator (TCXO) and
crystal.
-
The device incorporates a battery input,
disconnect the main power supply and maintains accurate timekeeping.
-
Integrated oscillator improve long-term accuracy
of the device and reduces the number of components of the production line.
-
DS3231 available in commercial and industrial
temperature ranges, using a 16-pin 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.
-
Clock operates in either the 24 hours or band / AM
/ PM indication of the 12-hour 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 temperature-compensated 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.
-
/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).
-
Temperature sensor accuracy is ± 3 ° C. On-chip
power supply control circuit can automatically detect and manage the main and
standby power (i.e., low-voltage 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 re-power or voltage value
returns to within the allowable range, the on-chip reset function can be used to
restart the system microprocessor.
Note:battery excluded
