DS1339U-33 Description

Short technical summary and product information.

The DS1339U-33 from Analog Devices is a serial real-time clock (RTC) IC that manages all timekeeping functions, including seconds, minutes, hours, date, month, day of the week, and year with leap-year compensation valid up to 2100. It offers two programmable time-of-day alarms and a programmable square-wave output.

 

This device interfaces with most microcontrollers via an I2C serial interface. It operates within a voltage range of 1.3V to 3.7V and has a typical current consumption of 200µA at 5.5V. The operating temperature range is -40°C to 85°C.

 

Key features include automatic power-fail detect and switch circuitry, trickle-charge capability, and an oscillator stop flag. The DS1339U-33 is available in a compact 8-uMAX/uSOP surface-mount package, specifically an 8-TSSOP, 8-MSOP (0.118", 3.00mm Width).

 

Applications for this RTC include handheld devices, consumer electronics, office equipment, medical devices, and telecommunications equipment.
