* Made of high quality material, durableand practical to use
* DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device has a battery input, disconnects the main power and maintains accurate timing. Integrated oscillation The device improves the long-term accuracy of the device and reduces the number of components in the production line.The DS3231 is available in a 16-pin 300mil SO package and can be used in commercial and industrial temperature ranges.
* RTC keeps the information of seconds, minutes, hours, date, date, month and year. In the case of less than 31 days per month, the end date will be adjusted automatically, including the correction of leap year. The clock is in 24-hour or 12-hour format With / AM / PM indication operation. Provides two configurable alarm clocks, and can set the calendar to square wave output. Address and data are transmitted serially through the I2C offerirectional bus.
* A precision temperature-compensated voltage reference and comparator circuit monitors the state of VCC to detect power failure, provides a reset output, and automatically switches to standby power when necessary. In addition, the / RST pin is monitored to manually generate a μP reset.
* To save time and increase accuracy, the DS3231 also has some other features that extend other functions of the system host and a series of options. The device integrates a very accurate digital temperature sensor that can be accessed through the I2C * interface (at the same time) The accuracy of this temperature sensor is ± 3 ° C. The on-chip power control circuit can automatically detect and manage the main power and backup power (i.e. low voltage battery) to switch between power sources. If the main power fails, the device can continue Provide accurate time and temperature, performance will not be affected. When the main power is re-powered or the voltage value returns to the allowable range, the on-chip reset function can be used to restart the system Size(L*W*H): 38mm * 22mm * 14mm(Approx.)
* Working Voltage: 3.3-5 .5 V
* Clock Chip: High-Precision Clock Chip Ds3231
* Clock Accuracy: 0-40degree Celsius, accuracy is 2ppm, error is about 1 minute
* With two calendar alarm clocks
* Programmable square wave output
* Real-time clock generator, including timing of seconds, minutes, hours, date, date, month and year, and provide year-to-year leap compensation
* Chip temperature sensor with ± 3degree Celsius accuracy
* Memory Chip: AT24C32 (Storage Capacity 32K)
* IIC bus interface, the maximum transmission speed is 400KHz (working voltage is 5V)
* Can be cascaded with other IIC devices, and the 24C32 address can be shorted to A0 / A1 / A2 to modify the default address to 0x57
* With rechargeable battery LIR2032, to ensure that the clock will move normally after the system is powered off
* Packing: Single Anti-Static Packaging
