DS1746W-120 Description

Short technical summary and product information.

The Analog Devices / Maxim Integrated DS1746W-120 is a Y2K-compliant, nonvolatile timekeeping RAM with an integrated Real-Time Clock, Crystal, and Power-Fail Control Circuit. It features 128KB of memory and operates within a voltage range of 2.97V to 3.63V.

 

This device offers a Parallel interface and operates at temperatures from 0°C to 70°C. Key features include leap year compensation valid up to the year 2100, a battery voltage-level indicator, and power-fail write protection. The clock registers are accessed identically to the static RAM, residing in the eight top RAM locations.

 

Packaged in a 32-EDIP module, the DS1746W-120 is designed for through-hole mounting. It is suitable for applications requiring reliable timekeeping and nonvolatile data storage, even in the absence of power for extended periods.
