DS1302S+T&R Description

Short technical summary and product information.

The Analog Devices DS1302S+T&R is a real-time clock and calendar chip designed for efficient timekeeping functions. It manages seconds, minutes, hours, day of the month, month, day of the week, and year, including leap-year compensation valid up to 2100. The chip includes 31 bytes of battery-backed general-purpose RAM for data storage.

 

Interfacing with microcontrollers is simplified through a 3-wire serial interface, supporting both single-byte and burst mode data transfers. The device operates over a voltage range of 2V to 5.5V and consumes very low power, drawing less than 300nA at 2.0V, which extends battery backup run time. It supports both 12-hour and 24-hour formats with an AM/PM indicator.

 

This IC is housed in an 8-SOIC package, minimizing space requirements on printed circuit boards. The operating temperature range is 0°C to 70°C, making it suitable for a variety of applications. Key features include leap year compensation, NVSRAM, and a trickle-charger.

 

Designed for surface mount applications, the DS1302S+T&R is a reliable component for embedded systems requiring accurate timekeeping and data retention.
