DS1685E-3 Description

Short technical summary and product information.

The Analog Devices / Maxim Integrated DS1685E-3 is a Real Time Clock (RTC) IC designed for applications requiring accurate timekeeping. It incorporates a Clock/Calendar function with a parallel interface, making it compatible with existing BIOS for DS1287 functions. The device offers 242 bytes of battery-backed Non-Volatile Static RAM (NVSRAM) for data storage.

 

Key electrical specifications include an operating voltage range of 2.5V to 3.7V and a typical current consumption of 2mA at 3V. It supports both 12-hour and 24-hour time formats (HH:MM:SS) and a YY-MM-DD-dd date format. Enhanced features include Y2K compliance, an alarm function, and a 32kHz output for power management. The DS1685E-3 also includes a 64-bit silicon serial number and leap year compensation valid through 2099.

 

This IC is available in a 24-TSSOP package with a surface mount mounting type. It operates within a temperature range of 0°C to 70°C. The datasheet also mentions an industrial temperature range of -40°C to +85°C for other variants. The device supports operation with either a 6pF or 12.5pF crystal, selectable via a dedicated bit.

 

Applications for the DS1685E-3 include embedded systems, utility meters, security systems, and network hubs, bridges, and routers.
