Basic description:
SHT1302 is a three-line serial clock timing chip that includes real-time clock and calendar functions. It can easily be connected to a microprocessor through a simple three-line interface.

They are (1) YRSTB (2) YSCLK (3) YI/O. Data can access 1 byte at the same time or 8 bytes in multi-byte mode. SHT1302 provides information on seconds, minutes, hours, weeks, dates, months and years. According to actual or leap year requirements, the monthly date will be adjusted automatically. In addition, the clock chip can be operated in a 12-hour or 24-hour system with morning/afternoon separation. An external 32. 768KHz vibration provides the correct clock inside the chip.
