Elevate your microcontroller projects with Kunkune’s DS1302 Real-Time Clock Module. This state-of-the-art module not only keeps track of time but also offers a static RAM for seamless communication with microcontrollers. Designed for precision and efficiency, it’s the perfect addition to your electronic toolkit.

Real Time Clock Module -DS1302 Key Features:

  • Accurate Timekeeping: Provides real-time data including seconds, minutes, hours, days, weeks, months, and years. It even adjusts for the number of days in each month and leap years.
  • Efficient Communication: Features a simple 3-wire interface – (1) RST reset, (2) I/O data lines, and (3) SCLK serial clock.
  • Low Power Consumption: Maintains data and clock information with a power consumption of less than 1mW.
  • Extended Calendar: Capable of calculating time up to the year 2100.
  • Static RAM: Comes with 31 bytes of 8-bit temporary data storage.
  • Flexible Data Transfer: Supports both single-byte transfer and multi-byte transmission character group mode.
  • Compact Design: Available in an 8-pin DIP package or an optional 8-pin SOIC package for surface mounting.
  • Wide Operating Voltage: Functions efficiently between 2.0V to 5V.
  • Temperature Resilient: Operates effectively in temperatures ranging from 0° to 70°.

Real Time Clock Module -DS1302 Specifications:

  • PCB Size: 44mm x 23mm x 1.6mm with 4 positioning holes (diameter 3.1mm).
  • Backup Battery: Uses a genuine CR2032 celestial sphere battery (3V, 260mAh). Note: Battery is non-rechargeable and not included in the package.
  • Crystal Precision: Features a 32.768KHz Japanese imported crystal with a matching capacitance of 6pF.
  • Chip Design: The 8-pin plug-in DS1302 chip is conveniently placed above the IC Block for easy replacement.
  • Compatibility: Module operates with both 3.3V and 5V, making it suitable for 5V and 3.3V microcontrollers.
  • Wiring: VCC → +5V/3.3V, GND → GND, CLK → P02, DAT → P01, RST → P00.

Dimensions: 43 x 23 mm
