This RTC maintains seconds, minutes, hours, day, date, month, and year information. In this module, the date is set based on whether the month is 29, 30 or 31 days and also it is leap year or not. This module can also be used in 12-hour and 24-hour formats.</p><h4 style="margin-right: 0px; margin-bottom: 14px; margin-left: 0px; padding: 0px; border-color: rgb(229, 229, 229); line-height: 34px;"><span style="margin: 0px; padding: 0px; border-color: rgb(229, 229, 229);"><span style="margin: 0px; padding: 0px; border-color: rgb(229, 229, 229);">Features:</span></span></h4><ul style="margin-right: 0px; margin-bottom: 30px; margin-left: 0px; padding: 0px; border-color: rgb(229, 229, 229);"><li style="margin: 0px; padding: 0px 0px 5px; border-color: rgb(229, 229, 229); line-height: 22px; list-style: inside none disc;">All that might be used is that in addition to the two required ports of SDA and SCL, the ints and COT that might be used are also cited.</li><li style="margin: 0px; padding: 5px 0px; border-color: rgb(229, 229, 229); line-height: 22px; list-style: inside none disc;">Spare battery: when the system is out of power, the backup battery will power PCF8563 chip, PCF8563 low power consumption, and ensure that the battery can be used for normal power supply for ten years.</li><li style="margin: 0px; padding: 5px 0px; border-color: rgb(229, 229, 229); line-height: 22px; list-style: inside none disc;">Crystal vibration: the new original product crystal vibration, guaranteed the chip PCF8563 stable, accurate time.</li><li style="margin: 0px; padding: 5px 0px 0px; border-color: rgb(229, 229, 229); line-height: 22px; list-style: inside none disc;">The advantage of the chip itself: in the actual project of the shop owner, a variety of clock chips have been applied, and it is found that this chip of philips is the most stable, the most accurate and the lowest power consumption.
