Integrated Circuits (ICs)

RTCI2CClockCalendar

The DS1307ZN+T&R is a classic I²C real-time clock (RTC) IC with 56 bytes of battery-backed NV SRAM, suitable for timekeeping in embedded systems.

Best for

  • General purpose timekeeping
  • Battery-backed RTC applications

Avoid if

  • High-precision timing requirements (requires external crystal)
  • Low-voltage (3.3V) systems without level shifting

Check before use

  • Crystal oscillator circuit layout
  • I²C bus pull-up resistors
