آی سی ساعت DS3231SN پکیج SOP16

Description:

The 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, and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line.
The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package.
The DS3231 is a serial RTC driven by a temperature compensated 32kHz crystal oscillator.

Applications:
Servers
Telematics
Utility Power Meters
GPS
