DS12R885S-33+ Description

Short technical summary and product information.

The DS12R885S-33+ is a Real Time Clock (RTC) integrated circuit from Analog Devices / Maxim Integrated, designed for embedded systems, utility meters, and security systems.

 

This device provides essential timekeeping functions including seconds, minutes, hours, day, date, month, and year with leap-year compensation up to 2100. It supports both 12-hour and 24-hour formats. Key features include a time-of-day alarm, three maskable interrupts, and a programmable square-wave output. The RTC also includes 114 bytes of battery-backed Non-Volatile Static RAM (NVSRAM) for data storage.

 

Designed for reliability, the DS12R885S-33+ features automatic power-fail detection and switchover to a backup supply. It supports trickle-charging for a rechargeable battery or supercapacitor. The device operates within an industrial temperature range of -40°C to 85°C and utilizes a parallel interface for communication.

 

The DS12R885S-33+ is supplied in a 24-SOIC surface-mount package.
