DS1689 Description

Short technical summary and product information.

The Analog Devices DS1689 is a Real-Time Clock (RTC) integrated circuit designed for accurate timekeeping and calendar functions. It incorporates NVSRAM with 114 bytes of user memory, providing non-volatile storage for critical data.

 

The device features a parallel interface for easy integration into various systems. It supports both 12/24 hour time formats and YY-MM-DD-dd date formats, offering flexibility in data representation. The operating voltage range is from 2.5V to 3.7V for battery operation and 2.7V to 5.5V for supply voltage, with typical current consumption of 2mA at 3V and 3mA at 5V.

 

Designed for standard operating conditions, the DS1689 has an operating temperature range of 0°C to 70°C. It is available in a 28-PDIP (Through Hole) package, suitable for through-hole mounting applications. Enhanced features include automatic battery backup and write protection to external SRAM, power control circuitry, and leap year compensation valid up to 2100.

 

This IC is compatible with existing BIOS for original DS1287 functions and is available in industrial temperature versions. It also offers a 32kHz output for power management applications.
