DS3231 AT24C32 IIC
Precision RTC Real Time Clock Memory Module For Arduino
|
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
- Module parameters:
- Size: 38mm (length) * 22mm (W) * 14mm (height)
- Operating voltage :3.3 - 5 .5 V
- Clock chip: high-precision clock chip DS3231
- Clock Accuracy :0-40 ℃ range, the accuracy
2ppm, the error was about 1 minute
- Calendar alarm clock with two
- Programmable square-wave output
- Real time clock generator seconds, minutes,
hours, day, date, month and year timing and provide valid until the year
2100 leap year compensation
- Chip temperature sensor comes with an accuracy
of ± 3 ℃
- Memory chips: AT24C32 (storage capacity 32K)
- IIC bus interface, the maximum transmission
speed of 400KHz (working voltage of 5V)
- Can be cascaded with other IIC device, 24C32
addresses can be shorted A0/A1/A2 modify default address is 0x57
- With rechargeable battery LIR2032, to ensure
the system after power failure, the clock move any natural normal
- Wiring instructions (with Arduino uno r3
for example):
SCL → A5
SDA → A4
VCC → 5V
GND → GND
- Note:
Transition: 1cm=10mm=0.39inch
No retail package.
Please allow 1-3mm error due to manual measurement. pls make sure you do
not mind before you bid.
