DS1306EN Description

Short technical summary and product information.

The DS1306EN is a serial alarm real-time clock IC manufactured by Analog Devices / Maxim Integrated. It is designed to manage all timekeeping functions, including counting seconds, minutes, hours, date, month, day of the week, and year, with leap-year compensation valid up to 2100.

 

This RTC features a 96-byte battery-backed NV RAM for data storage and two time-of-day alarms. It supports standard serial port interfaces, including Motorola SPI modes 1 and 3, and a standard 3-wire interface. The device operates over a wide voltage range of 2.0V to 5.5V and offers an optional industrial temperature range of -40°C to +85°C.

 

The DS1306EN is available in a compact 20-pin TSSOP package, minimizing space requirements in applications. It also includes dual power supply pins for primary and backup power, with an optional trickle charge output to the backup supply, ensuring continuous timekeeping.

 

Key features include alarm functionality, leap year compensation, NVSRAM for non-volatile data storage, square wave output, and a trickle-charger. The device supports both 12/24 hour time formats and YY-MM-DD-dd date formats.
