DS1302+ Description

Short technical summary and product information.

The Analog Devices DS1302+ is a Real Time Clock (RTC) and calendar chip designed for precise timekeeping functions. It manages seconds, minutes, hours, date, month, day of the week, and year, including leap-year compensation valid up to 2100. The device includes 31 bytes of battery-backed general-purpose RAM for data storage.

 

Interfacing with microcontrollers is simplified through a 3-wire serial interface (CE, I/O, SCLK), supporting both single-byte and burst mode data transfers. The DS1302+ operates on low power, consuming less than 300nA at 2.0V, extending battery backup run time. It supports a wide operating voltage range from 2.0V to 5.5V.

 

Available in an 8-pin PDIP package, the DS1302+ is suitable for through-hole mounting. It offers features such as leap year compensation, NVSRAM, and a trickle-charger, making it a versatile component for various timekeeping applications. The device operates within a temperature range of 0°C to 70°C.
