    DS12887+ Product overview

    The DS12887+ is a real time clock in 24 pin DIP package. This device provides real time clock/calendar, one time of day alarm, three maskable interrupts with common interrupt output, programmable square wave and 114bytes of battery backed static RAM. The DS12887 integrates quartz crystal and lithium energy source into 24 pin encapsulated DIP package. The date at end of the month is automatically adjusted for months with fewer than 31 days including correction for leap years. The devices also operate in either 24hour or 12hour format with an AM/PM indicator. A precision temperature compensated circuit monitors the status of VCC. If primary power failure is detected, the device automatically switches to backup supply. It is accessed through multiplexed byte wide interface which supports both Intel and Motorola modes.

    DS12887 Product overview

    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 battery-backed 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. The DS12C887 adds a century byte at address 32h. 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 devices also operate in either 24-hour or 12-hour format with an AM/PM indicator. A precision temperature-compensated circuit monitors the status of VCC. If a primary power failure is detected, the device automatically switches to a backup supply. A lithium coin-cell battery can be connected to the VBAT input pin on the DS12885 to maintain time and date operation when primary power is absent. The device is accessed through a multiplexed byte-wide interface, which supports both Intel and Motorola modes.
