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.
