DS1302 Real-Time Clock Module (No Battery Included)

The DS1302 Real Time Clock Module is a high-precision, low-power clock chip designed for use in various electronic projects. It features a real-time clock/calendar and 31 bytes of static RAM, making it ideal for accurate timekeeping and data storage applications. The module communicates with a single-chip microcomputer through a simple serial interface, requiring only three lines for operation: RST, I/O data line, and SCLK serial clock.

  Key Features:  

• Real-time clock/calendar with seconds, minutes, hours, days, weeks, months, and years information
• Automatic adjustment for leap years and number of days in a month
• AM/PM or 24/12-hour format selection
• Low power consumption (less than 1mW) for data and clock information retention
• Simple 3-wire interface
• Compatible with TTL Vcc=5V
• Double power supply for main and backup power
