Real-Time Clock

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 w

Real Time Clock

DESCRIPTION The DS1287A is identical to the DS1287 with the addition of the RAM clear pin. For a complete description of operating conditions, electrical and mechanical characteristics, bus timing, and pin descriptions see the DS12887A data sheet. FEATURES •Drop-in replacement for IB
