General Description

The DS12885, DS12887, and DS12C887 real-time clocks (RTCs) are designed to be direct replacements for the DS1285 and DS1287.

The devices provide a real-time clock/calendar, one time-of-day alarm, three maskable interrupts with a common interrupt output, a programmable square wave, and 114 bytes of batterybacked static RAM (113 bytes in the DS12C887 and DS12C887A).

The DS12887 integrates a quartz crystal and lithium energy source into a 24-pin encapsulated DIP package.

Overview

Rev 0; 6/05 Real-Time Clock General.
