DESCRIPTION
The DS1315 Phantom Time Chip is a combination of a CMOS timekeeper and a nonvolatile memory
controller. In the absence of power, an external battery maintains the timekeeping operation and provides
power for a CMOS static RAM. The watch keeps track of hundredths of seconds, seconds, minutes,
hours, day, date, month, and year information. The last day of the month is automatically adjusted for
months with less than 31 days, including leap year correction. The watch operates in one of two formats:
a 12-hour mode with an AM/PM indicator or a 24-hour mode. The nonvolatile controller supplies all the
necessary support circuitry to convert a CMOS RAM to a nonvolatile memory. The DS1315 can be
interfaced with either RAM or ROM without leaving gaps in memory.
OPERATION
The block diagram of Figure 1 illustrates the main elements of the Time Chip. The following paragraphs
describe the signals and functions.
