DS1302 Clock Module Real-Time Clock Module RTC for AVR ARM
The DS1302 is a low-power, trickle-charge real-time clock (RTC) module that tracks seconds, minutes, hours, date, month, day, and year with leap-year compensation up to 2100. It uses a 3-wire serial interface (RST, I/O, SCLK) to communicate with microcontrollers and operates at 2.0V-5.5V, consuming <300nA at 2.0V for battery backup.

The DS1302 module is designed to maintain accurate time (date, hours, minutes, seconds) even when the main system power is off. It is highly popular in Arduino, PIC, and ARM projects for data logging, timers, and alarm systems. It automatically handles leap-year adjustments.
Pin Configuration:
- VCC: Power Supply (2.0V – 5.5V)
- GND: Ground
- I/O: Data Input/Output
- SCLK: Serial Clock
- RST (CE): Reset/Chip Enable
