The DS1306N+ from Maxim Integrated is a highly versatile, serial real-time clock (RTC) with dual programmable alarms. This integrated circuit (IC) is designed to provide precise time and date information, with the added benefit of an SPI or 3-wire interface for seamless integration into a variety of microcontroller-based systems.

Key Features

• Real-Time Clock/Calendar: Tracks time in hours, minutes, and seconds, and the date in months, days, and years with leap-year compensation valid up to the year 2100.
• Dual Programmable Alarms: Allows users to set two separate alarms, which can be programmed to trigger on a minute, hourly, daily, or monthly basis.
• Serial Interface: Offers both SPI and 3-wire interfaces for communication with microcontrollers and other digital systems.
• Low Power Consumption: Designed for power-sensitive applications, the DS1306N+ operates in either 24-hour or 12-hour formats with an AM/PM indicator.
• Trickle-Charge Capability: Includes an integrated trickle charger to maintain the timekeeping operation by connecting to a backup battery or supercapacitor.
• 56-Byte, Battery-Backed, General-Purpose RAM: Provides additional storage which is protected during power loss by the backup battery.

Applications

The DS1306N+ is ideal for a broad range of applications, such as:

• Embedded Systems
• Utility Meters
• Security Systems
• Handheld Devices
• Industrial Controllers
