The DS1306 from Maxim Integrated is a versatile Serial Alarm Real-Time Clock (RTC) that provides a comprehensive timekeeping solution for embedded systems. Designed to maintain accurate time and date information, this RTC operates over the full industrial temperature range and communicates via a simple serial interface, compatible with most microcontrollers.

Key Features

• Dual Programmable Alarms: The DS1306 includes two programmable time-of-day alarms, allowing for the scheduling of events or wake-up signals.
• Serial Interface: It features a serial interface that is SPI or 3-wire compatible, providing flexibility in system design and ensuring ease of integration.
• Low Power Consumption: Designed for power-sensitive applications, the DS1306 operates with very low power consumption, preserving battery life in portable devices.
• Battery Backup Input: The device includes a battery input, maintaining accurate timekeeping even when the main power supply is interrupted.
• Programmable Square-Wave Output: A programmable square-wave output is provided, which can be used for various applications such as periodic system wake-ups or as a clock reference signal.
• Large Clock Register Set: The DS1306 contains 96 bytes of NV SRAM and 8 clock registers separated from the memory to avoid corruption.
