FEATURES
Keeps track of hundredths of seconds, seconds, min-
utes, hours, days, date of the month, months, and
years
Converts standard 8K x 8 and 32K x 8 CMOS static
RAMs into nonvolatile memory
Embedded lithium energy cell maintains watch infor-
mation and retains RAM data
Watch function is transparent to RAM operation
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 DS1216C SmartWatch/RAM is a 28–pin, 600 MIL
wide DIP socket with a built–in CMOS watch function, a
nonvolatile RAM controller circuit, and an embedded
lithium energy source. It accepts either an 8K x 8 or a
32K x 8 JEDEC bytewide CMOS static RAM. When the
socket is mated with a CMOS SRAM, it provides a com-
plete solution to problems associated with memory vol-
atility and uses a common energy source to maintain
time and date. A key feature of the SmartWatch is that
the watch function remains transparent to the RAM.
See the DS1216B SmartWatch/RAM 16/64K data sheet
for technical details.
