FEATURES
Adds timekeeping to any 32–pin JEDEC bytewide
memory location
Embedded lithium energy cell maintains calendar
time for more than 10 years in the absence of power
Timekeeping function is transparent to memory oper-
ation
Keeps track of hundredths of seconds, seconds, min-
utes, hours, days, date of the month, months, and
years
Month and year determine the number of days in each
month; leap year compensation valid up to 2100
Lithium energy source is electrically disconnected to
retain freshness until power is applied for the first time
Proven gas–tight socket contacts

DESCRIPTION
The DS1216F SmartWatch/ROM is a 32–pin, 600 mil–
wide DIP socket with a built–in CMOS timekeeper and
an embedded lithium energy source to maintain time
and date. It accepts any 32–pin bytewide ROM or vola-
tile RAM. A key feature of the SmartWatch is that the
timekeeping function remains transparent to the
memory device placed above. The SmartWatch moni-
tors V
CC
for an out–of–tolerance condition. When such
a condition occurs, an internal lithium energy source au-
tomatically switches on to prevent loss of time and cal-
endar data.
Using the SmartWatch saves PC board space since the
combination of SmartWatch and the mated memory de-
vice takes up no more area than the memory alone. The
SmartWatch uses pins 1, 10, 12, 13, 22, and 24 for time-
keeper control. All pins pass through to the socket re-
ceptacle except for pin 22 (CE), which is inhibited during
the transfer of time information.
See the DS1216E SmartWatch/ROM/64/256K data
sheet for technical details.
