The DS1339BU+T is a low-power serial real-time clock (RTC) from Analog Devices / Maxim Integrated. This clock/date device features two programmable time-of-day alarms and a programmable square-wave output. Data is transferred serially via an I2C bus.
Key specifications include a supply voltage range of 1.3V to 3.7V and an operating temperature range of -40°C to 85°C. It consumes a typical current of 200µA at 1.71V to 5.5V. The device provides seconds, minutes, hours, day, date, month, and year information, with automatic adjustment for month lengths and leap year corrections valid up to 2200. It supports both 12-hour and 24-hour formats.
Additional features include automatic power-fail detection and switch circuitry to maintain timekeeping during power interruptions. It supports high-ESR crystals up to 100kΩ, allowing for optimization in cost and space. The DS1339BU+T is available in an 8-uMAX/uSOP package and is designed for surface mounting.
Applications for this RTC include handheld devices, consumer electronics, office equipment, medical devices, and telecommunications infrastructure.
The operating voltage range is 1.3V to 3.7V.
The operating temperature range is -40°C to 85°C.
The DS1339BU+T is available in an 8-uMAX/uSOP package and an 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) package.
The RoHS status is RoHS3 Compliant.
Key features include alarm, leap year compensation, square wave output, and trickle-charger functionality.
The DS1339BU+T uses an I2C, 2-Wire Serial interface.
