Detail
Specification:
DS3231 is a 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. The DS3231 is 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. The 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. 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. 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.
