The DS1306EN+T&R 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 IC includes 96 bytes of battery-backed NV RAM for data storage and supports two time-of-day alarms that are programmable. It offers clock outputs of 1Hz and 32.768kHz. The device interfaces with most microcontrollers via a standard serial port, supporting Motorola SPI Modes 1 and 3 or a standard 3-wire interface. Burst mode is available for reading and writing successive addresses in the clock or RAM.
Featuring dual-power supply pins for primary and backup power, it also offers an optional trickle charge output for the backup supply. The operating voltage range is from 2.0V to 5.5V, and it operates within an industrial temperature range of -40°C to +85°C. The DS1306EN+T&R comes in a compact 20-pin TSSOP package, minimizing space requirements.
Key specifications include a 96-byte memory size, HH:MM:SS (12/24 hr) time format, YY-MM-DD-dd date format, and SPI interface. The operating current for timekeeping ranges from 25.3µA to 81µA at 2V to 5V. The package is surface mountable.
