General Description

The DS12885 real-time clock plus RAM is designed to be a direct replacement for the DS1285.

The DS12885 is identical in form, fit, and function to the DS1285, and has an additional 64 bytes of general purpose RAM.

Access to this additional RAM space is determined by the logic level presented on AD6 during the address portion of an access cycle.
