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 fewer 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.
