The DS1307Z+T&R is a serial real-time clock (RTC) from Analog Devices / Maxim Integrated. This low-power device manages all timekeeping functions, including seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. It features a 56-byte battery-backed general-purpose RAM with unlimited writes and a programmable square-wave output signal.
The clock operates in either 24-hour or 12-hour format with an AM/PM indicator. It includes a built-in power-sense circuit that detects power failures and automatically switches to a backup supply, ensuring continuous timekeeping operation. The device uses an I2C serial interface for communication with microcontrollers.
Designed for surface mounting, the DS1307Z+T&R comes in an 8-SOIC package with dimensions of 0.154 inches (3.90mm) width. It operates within a temperature range of 0°C to 70°C and requires a supply voltage between 4.5V and 5.5V, with a battery voltage range of 2V to 3.5V. The timekeeping current consumption is a maximum of 200µA at 5V.
Key features include leap year support, NVRAM, and a square-wave output. The date format is YY-MM-DD-dd, and the time format is HH:MM:SS (12/24 hr). This component is suitable for applications requiring accurate timekeeping and data storage.
