*This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.

The VT82885 Real Time Clock is designed to be a direct replacement for the DS12885. The VT82885 is identical in form, fit and function to the DS12885. It has 114 bytes of general purpose RAM. Access to this RAM space is determined by the logic level presented on AD6 during the address portion of an access cycle. An external crystal and battery are the only components required to maintain time-of-day and memory status in the absence of power. A complete description of operating conditions, electrical characteristics, bus timing and pin descriptions follows.
