DS1306EN+

The DS1306EN+ is a Real Time Clock (RTC) 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.

Key features include a 96-byte battery-backed NV RAM for data storage, two time-of-day alarms, and clock outputs at 1Hz and 32.768kHz. The device supports standard serial port interfaces, including Motorola SPI Modes 1 and 3, and a standard 3-wire interface, with burst mode for efficient reading and writing of successive addresses.

With dual power supply pins for primary and backup power, and an optional trickle charge output, the DS1306EN+ offers flexibility in power management. It operates over a wide voltage range of 2.0V to 5.5V and is available in an optional industrial temperature range of -40°C to +85°C. The component is housed in a compact 20-pin TSSOP package, minimizing space requirements in applications.

This RTC is suitable for a wide range of applications requiring accurate timekeeping and data storage, such as embedded systems, data loggers, and portable devices. Its robust feature set and reliable performance make it a valuable component for designs needing precise time management.
