If a primary power failure is detected, the device automatically switches to a backup supply. A precision temperature-compensated circuit monitors the status of VCC. The devices also operate in either 24-hour or 12-hour format with an AM/PM indicator.
For all devices, the date at the end of the month is automatically adjusted for months with fewer than 31 days, including correction for leap years.
The DS12887 integrates a quartz crystal and lithium energy source into a 24-pin encapsulated DIP package. 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 battery backed static RAM (113 bytes in the DS12C887 and DS12C887A). The DS12885, DS12887, and DS12C887 real-time clocks (RTCs) are designed to be direct replacements for the DS1285 and DS1287.
